On June 25, 1961 Elvis visited RCA Studio B in Nashville/Tennessee to record material for future single releases. Finally "(Marie's The Name) His Latest Flame" and "Little Sister" made it onto a 45, the other tracks were kept to be released on an album.

In his "Duffy Duck Voice" the king intones the title and produces some low noises. The first take already is a complete performance. Because this is the first try, Elvis doesn't know how to phrase each and everything (especially the words "kiss me quick") and also sings less zesty. The final arrangement is yet to be found, in contrast to the master we hear The Jordanaires during the bridge. Take number two is played a tad faster, at times Elvis appears to be a bit distracted. Before the 3rd take the arrangement of the harmony vocals during the bridge have been altered, on take number 4 the part of The Jordanaires is gone. Elvis still fights with the phrasing of the words "kiss me quick", take 5 is canceled after the guitarist missed a break. Despite being a false start, everyone agrees, that this try was the best so far. The 7th attempt finally sounds like the master recording. At least considering the arrangement. Elvis goofs on the timing, so the track cannot be released anyway. The next try is very good and I am pretty sure that the king would have approved it for release in the 1970s. However, back in 1961 he still was a perfectionist and didn't accept anything below the 100% mark. Take 9 is another flase start due to a mistake by the guitar player. During the 9th attempt Elvis toys a bit with the phrasing and the melody. He's trying out several things. During take number 10 the king's voice cracks on the word "never". Now Elvis tries to phrase the words "kiss me quick" in a different way. It works, but doesn't sound as good as before. With take 12 the master is in the can.

The guitarist practices his part, Elvis jokes a bit. Afterwards we get to hear an intimate sounding first take. Of course it's not perfect, but considering that this is the first try, it sounds nothing but great. The second take is killed off by the producer after the king phrased "...her memory is with you yet" not too well. "Elvis, let's try one more, please" he says. Before the official recording begins, the king and one of the harmony singers rehearse this very line. Still the singer fails at the same spot, the next try doesn't even get past the choir intro. The Jordanaires turn it into a joke and lower the key, which causes some laughter. The next take also doesn't get old, because Elvis fails to sing "...and you know". He stops the performance and admits "I'm sorry, I'm sorry, I goofed it". Before take number 5 is started, the guitarist switches from his acustic guitar to an electric one. Elvis now sings with more energy, in general the result sounds very good. The next take is nothing but short false starts. First the king stops The Jordanaires, then he ceases to sing and says "Hold it, gimme another start". It turns out to be another complete performance and sounds as great as the 5th attempt. Still the king and his crew tape another one, before they realize, that they cannot improve a perfect rendition. Until this day I cannot imagine anyone singing this song better than Elvis does it here.

Nobody appears to be challenged by the ballad, take 1 already sounds perfect. Now Elvis doesn't get into the song and says "Hold it, I'm sorry". He tries again, but is interrupted by the producer. The third try, still considered to be take 2, works just fine. The king stops to sing after "my love", the next try is killed off by the producer because the performance sounds a tad lame. Takes 4 to 6 are complete performances, the final one is selected as basis for the master. However, Elvis still isn't satisfied with the ending and produces two workpart takes. The first one doesn't work out, but the second try sounds as the king wants it to. FTD continues the "I'm Yours" session with this very take, which was used in 1965 on the accordant single. Until today it is unknown whether RCA wanted to offer an alternative performance or if it simply was a mistake. For Elvis this version was nothing but a intermediate stage. He wanted to record a harmony vocal to duet with himself. The first three tries are failtures, because the king can't hear himself properly through his headphones and doesn't really know when to start. Finally everything works out. The harmony overdub doesn't feature just Elvis' vocals, but also the spoken part as well as the organ solo. Takes 2 to 4 are false starts only, the 5th and 6th attempts are complete performances. The album master of "I'm Yours" is the splice of take 6 and workpart take 2, combined with the additional vocals from harmony take 6 and the spoken bridge from harmony take 5.

First the band fails to play the intro, then Elvis stops the walkthrough with a laughing "Just play that much back". In contrast to the released version the guitar is quite prominent and the beat is tapped. It sounds more like a rehearsal than a serious attempt to record the song. Another false start leads into the second take, but it doesn't sound less clumsy at all. Elvis hasn't any trouble to perform the song, but the arrangement leaves a lot to be desired. Before the recording is continued several changes are made. From now on the beat is played with a brush and accentuated by the bass. As a result everything sounds smoother. Elvis cancels take 5 after a short while by saying "Hold it", the next three attempts are false starts only. All of them are considered to be take 5. Number six works much better. The arrangement is set and the lead vocalist knows what to do. From now on it's all about the details. The 7th try is killed off after half a minute, but number 8 sounds perfect. The takes 9 to 11 are nothing but false starts. The first two attempts falter after 45 seconds or so, then the guitarist makes a mistake. Take 12 once again turns out to be a complete performance, but the wheels have come off and Elvis settles for take 8.

Before the recording starts, Steve Sholes rightfully calles "Little Sister" a potential classic. However, take 1 soon turns out to be history since Elvis fails to sing the first two words right. The second attempt is nothing more than two false starts. First, Scotty Moore misses his cue, then the king stops to sing after the first two words. In-between he says "I can hardly hear you". Finally take number 3 turns out to be a complete performance. The rhythm is different to the master and the guitar licks sound quite clumsy. Now Elvis sings much too soft and quickly apologizes himself by saying "Hold it, I'm sorry". By take number 5 the two drummers have figured out the right beat, but the signature guitar riffs are yet to be discovered. The recording is stopped after the band stumbles upon a supposed break. The 6th attempt is another complete performance. Apart from the guitar licks it already sounds similar to the master. Take 7 falters shortly before the minute mark, the next one is nothing more than two false starts. First, the intro is messed up. Then one of the drummers doesn't get it right. The 9th attempt starts with a technical issue and a false start. But then another complete performance is archived. The guitarist still hasn't found the classical licks, but plays the whole thing a tad more simple. Take number 10 is killed off, because once again the musicians miss the break. The 11th one is performed with more zest, but sounds a bit aimless and therefore is abandoned. With take 12 everything suddenly comes together. The beat is right, the guitarist plays harder and simpler and Elvis' vocals are right on the spot. With the final master in the can the session is closed and everyone is heading home.
