Here's a nice recording of Little Billy Wilson by Jane Rothfield. I don't know how
long it is because I only heard the snippet:
I'd look for other good 40-bar tunes like:
* Three Thin Dimes
* Three-way Hornpipe
* The Snoring Mrs. Gobiel
* the 5-part Fox Hunter's Jig
I know there are more, but that might be a start.
