Neither does Copernic, and it usually digs up a few that Google does not find.

There is a version I've Been Everywhere (In Texas) by Brian Burns, and I have heard one by George Fox that is different in the intro, and of course, Stompin' Tom gives it his original stamp as well, giving it a Canadian flavor.

I'll try to look those up over the next few days, but won't feel the least bit hurt if someone beats me to 'em.
