Back in the 1970's there was still a fleet of old trucks that used to hit the smaller towns in mid-Michigan; I think it was called Rosier's Circus and for all I know there's still running. They performed classic vaudville routines, had an old time string band, and I did make a reel-to-reel tape of their performance which would not be impossible to find.

READ 'EM AND WEEP by Sigmund Spaeth has a wealth of such songs from the 19th century, along with great notes; there's also MORE READ 'EM AND WEEP by the same author.
