If your nose is in a book, how the hell do you watch the lead singer (who shouldn't be using a book, if they're singing lead)?

And if you're not waching the lead, how bad can it get?

My own feeling is that I don't mind if people have books as a reminder, but the only real way to learn a song is by singing it.

By the way, any body who can read the words in Rise Up Singing in the light that is usually available around a campfire has earned my bitter envy. My eyes aren't all that good now, and I don't think they were ever that good.
