Or, follow the "Support Mudcat" links to one of the online music sources, and search album titles under "Music Hall" or "Vaudeville." You'll find a few that look interesting. CDNow, for one, will than suggest others in the category that might interest you.
I have one music hall CD I really like, one by tenor Jerry Hadley on RCA called "Golden Days - Rimberg/Friml/Herbert." Some aren't the humorous type that you might associate with "music hall" songs, but there are some real gems on the album.
