Value #5: Save a Tree: Memorize Your Song.

I've only been to one Sing(around) over the water, in Portland Oregon. There incredibly everyone had a ring binder full of every song anyone might sing so that they could all join in. When my freind (who lived in Portland) suggested they might let me (over from Emgland) on stage the assembled company was aghast that any individual should so hog the space.
May be unusual but I'll never forget it!
