Most of what you said there, Dick, is old hat. Yes we know all that. It's all been aired in this very thread of yours. You say there is no "correct version" of a tune. Well, I'll buy that. Believing that would ossify the music, you say. OK. But what do you think a bunch of dots on a page represent? One version, unchanging, someone's opinion of that tune, looking very authoritative in the book's fancy cover. An ossified tune!
