I have 5 or 6. Mostly use them as a jump off place to do my own arrangements. Then they move into my personal gig book that I've been working on since about '63, about 250 that I've done the arrangements for and perform, and a second book of a few thousand that I'll get to working on someday, that includes some that are written on napkins by candle light in a 60's coffeehouse trying to copy what the performer was doing.
