I agree with Jon..a large party format should not be subjected to "song circle" type rules...and there should be other rooms for those who prefer that format...(and maybe subgroups of those who like the blue books).. it doesn't work with a large, vigorous group whose purpose is not to be supportive of whatever but to produce the best music possible with the most incredible collection of voices you can imagine. And trust me, people won't like it if you impose the blue book on them at one of these groups. They will sneak off and leave to another area. mg
