Notes:

• "Less Than Zero" has a slightly different mix to the LP version.
• "Radio Sweetheart", Costello's first professional recording, was left off the album due to it having a different sound - it was the only track to prominently feature an acoustic guitar.
• Etched in the runoff for side A is "Elvis is King on This Side Too" & "A Porky Prime Cut". Side B contains "Elvis is King".
