One pretty good source that oughta be easy enough to find . . .
Go out and rent some Bette Midler concert videos. Hell, if you’re seriously into this kinda thing, go out and buy them- and study them.
Of course, Midler fans already know where I’m going with this, I’m directing you towards Midler’s Sophie Tucker character (yes, there was also a real life performer named Sophie Tucker). As Sophie, Midler recounts stories always revolving around Sophie, her boyfriend Ernie, and her best friend Clementine. Classic bawdy comedy kinda stuff. I think most of the material is made up of standard stock jokes, so feel free for practice purposes to steal the jokes, tell them to your friends to see if you can tell them as well as she does.
Look at The Sunshine Boys. The vaudeville sketch in the movie is quite similar to real sketches by such artists as Smith and Dale. They did the “Dr. Kronkite” sketch with jokes just as bad as you can imagine:
See the musical Rose, aka Gypsy, about the life of Gypsy Rose Lee. Mama Rose spends years trying to launch her daughter Louise’ career in Vaudeville, with intermittent success. Finally they are reduced to working a burlesque show. One of the strippers: “Vaudeville! Everybody knows there ain’t no Vaudeville no more except burlesque!”
