Rapunzel, were there some 'normal' cryptic clues to get you going, or were they all single letters?

It was just a normal, newspaper-type crossword, with 6 or 8 "theme" clues in the form of single letters. I actually had no idea what the answers to the theme clues would look like until I filled in enough letters in the first one to figure out what the author was getting at.

P.S. TEd, your "topless bars" clue made me laugh out loud.
