Thanks!
Some of these sound like what I'm looking for - any way to get the melodies to them?
Some of them I've been able to figure out or vaguely remember and can make sense of but of the one's I can't . . .

I'm particularly interested in the
Artful Codger's "What a queer bird...",
and the two from Joe f. I like those catches - they can be really fun.
Also Willa's "Beware the Law of Gravity"

but I have no idea of the tunes for them. I'm new to this whole forum thing - how do people get melodies?
