Well, I just picked the theme a week ago for the next house hoot at my house, and the theme is: 1st round=first names, later rounds=last names. And then this thread was started, so I'm wondering if guest,jb is someone on my folk society mailing list? Hmmmmmm.

Anyway, here are a few I'm considering:

Lorena
Little Maggie
Little Annie
Catfish John
Colleen Malone
Ginseng Sullivan
Hey Jude
Jack Haggerty
Jimmy Brown the Newsboy
John Hardy
John Henry
John Brown's Body
Johnny, I Hardly Knew You
Louise
and many, many others!
