Looking into some jazz terminology here, I came across a definition of "chorus" that says
One complete cycle of a tune, one time through from top to bottom
Also on that page, part of the definition of "verse" is
... Jazz players (and fakebooks) usually omit the verse...
That made me think that perhaps some early standards came from vaudeville or tin pan alley songs, where the verse was dropped.
If that's correct, would anyone have any examples? I'd like to be able to listen to the original as well as the dropped verse version.
