Here's my response to this - Not In The Book. I've probably mentioned this before on one of many threads on this hot topic.
Rise Up Singing is really a fine collection of songs to sing in groups, but not to be used in group singing. Does that make sense? - read my response above.

Like Deckman, above, I quit the Song Circle for the same reason.
On the other hand I go to a weekly "community sing" at Seattle's Dusty Strings music store. It is lead by two wonderful singers and instrumentalists - Kate Power and Steve Einhorn. They lead the songs and are the "house band." They have a loose-leaf notebook with many songs that they know quite well. People can use that book and suggest songs or bring multiple copies of a song they know and can lead. I usually bring a song each week, which I lead from memory. Unlike a song circle, the leaders know the songs - there is no going around the circle with people saying "let's sing that song, but I don't really know it" and everyone stumbling through a song that nobody knows. People are not leafing through a book to find a song because it is their turn. And most people who read the lyrics scan a line ahead and actually look up as they sing. It works quite well.

Cheers, S. in Seattle
