I learned to sing in church, with hymnals; and at Scout camp, without any printed lyrics. Through the years, I've come to know a lot of songs so well that I hardly glance at the hymnal, but I'm still glad I have it in hand. And yeah, I know about three hundred camp songs by heart; and I hate the thought of passing out song sheets at a campfire and have often fought parents who want them.

Still, most often I feel more comfortable if I have something to lean on if my memory fails; and I find a hymnal works best for group singing of most songs. I was raised singing with hymnals, and I guess I feel a bit offended by people say I can't sing as well as they do, simply because I usually sing from a book.
