Oh, Kat, I don't mind that at all, and often provide sheets when I'm teaching songs at workshops - but song sheets at a campfire are a travesty. Besides being a mess, people start complaining that they can't read the words, or they bring out flashlights. Part of the fun of a campfire song, is the teaching. It can be a challenge, but you can make it memorable if you ham it up the right way.
