Upcoming gig-song ideas?

Hey guys,
well im slowly learning that when i have a problem, drummer world is the best place. And that's not just a catchy slogan.
Anyway, me and a few mates have got a gig at a birthday party. The theme is 1920's but seeings as most of the 1920's music is mostly big band, it will be unsuitable for a 3 piece with drums acoustic/electric guitar and vocals. Sooo, do you guys have any ideas for some jazz songs that we could do that could tie into a 1920's theme. So far we've thought about two jazz standards, Moanin' and Autumn leaves. Thanks.
