On December 29, 1954 SUN Records released the third single of the newcomer. Once again the sales had lowered compared to the previous release. This time none of the tracks charted anywhere. In November 1955 RCA Victor took over and sold the 45 under their own brand. In the present both tracks are not too popular. On Spotify "Milkcow Blues Boogie" clocks in at 1.8 million streams, "You're A Heartbreaker" doesn't even reach the million mark.

Because SUN Records didn't produce individual picture sleeves for their releases, the single was sold in the usual SUN sleeve.

The single cannot be found on the streaming platforms. But RCA Victor included "Milkcow Blues Boogie" on the album "A Date With Elvis" (1959) and "You're A Heartbreaker" on the longplayer "For LP Fans Only" (1959).

Originally the song was named "Milkcow Blues" and was written and recorded by Kokomo Arnold in 1939. Elvis, Scotty and Bill played the song faster and used the by now established style of the Hillbilly Cat. To make it short: I don't like the tune at all. RCA Victor re-released it on the albums "A Date With Elvis" (1959) and "The Sun Sessions" (1976).

Even though the narrator offers a quite negative oppinion of his  ex-girlfriend, the melody is happy. The song by Jack Sallee is a tad on the leightweight side, but the tune stays with you. RCA Victor later included the track on "For LP Fans Only" (1959) and "The Sun Sessions" (1976).
