no...it is a book that a lot of people have. A cheat sheet is inocuous because a person has taken the time to at least partially know it...maybe she knows the tune and forgets the words. Now, the singing will still be better without it...I don't know why..if it is acoustical or what...some type of better communication that we evolved to hear...reading is basically a visual act. Singing is an oral/aural act. It calls on different parts of the brain. I don't know all the factors. But cheat sheets, while less preferable than knowing by heart, do not in any way compare to the way the BB is used...which is like a folk choir book. People know just enough to know they have heard the song somewhere, then try to patch it together. It can be quite painful. If they must use them, I would prefer that just one person used it for a cheat sheet, on a song they more or less knew and were just refreshing their memory on the words. I know there can be mental situations where memorization is not possible, and as always, we should accomodate that sort of problem. But how hard could it be to learn 2 songs say? Not that I have recently.
