Well, Steve, I just came from a very GOOD song circle. I've been listening to comments here about overuse of Rise Up Singing, and trying to introduce a few new songs, and encouraging people to look at each other at least while they're singing the chorus. It certainly adds life to the circle when people look at each other.
....and I couldn't help notice the pretty blonde sitting across from me, once I took off my reading glasses and got her in focus.
I'd say my song circle could have some fun with the songs you mentioned. Hope your next circle goes better.
