Song Request: This is driving me crazy!

by Alex
(California)

I was on a road trip and listening to old-school music on the radio. (It was on satilite, if that detail even matters.) Then all of these nostalgic songs started to play.

The one I can't find is sung by a man, or a male group.

They were singing something that sounds like 'Betty's dress.'

The song had a medium tempo, and sounds like an 80's song.

B-b-betty's dress!

I feel silly because I'm so unsure.

I am grateful for all help, thanks for reading!
