Elvis released three records on the Sun label in 1955:

• “You’re a Heartbreaker”/”Milkcow Blues Boogie” (January)
• “Baby Let’s Play House”/”I’m Left, You’re Right, She’s Gone” (April)
• “Mystery Train”/”I Forgot to Remember to Forget” (September)

None made the Billboard Pop charts, although the last two made the Country and Western charts.  Elvis signed with RCA Victor in November 1955.
