Boney Maroney is a rock standard by Larry Williams which has been covered by a lot of people. It's a song about a girl named Boney Maroney. The spelling has changed around.

The list includes Ritchie Valens and many more. It's curious that Mac would then sing about Boney Maroney being a guy when the original was about a girl.
