Sorry for posting this off-topic message... but there doesn't seem to be a forum for general discussion anymore and a lot of you guys are very knowledgeable about movie music, so...

Does anybody know the name of the jazz tune that's playing in the GI club in the movie Catch-22 during the scene where Yossarian dances with the tall italian woman (after bragging that he's the most renowned killer of fish in the whole United States Army Air Force)? I've had it stuck in my head for two days and I can't figure out what song it is!!! I'm pretty sure it was a pre-existing tune and not something composed specifically for the movie.

Thanks for any help you can give me.
