I don't know. Sometimes I think it can. I think, well I actually did about a three month period in the Washington, D.C. schools and we got a huge grant for this, to go around to the public schools with just this thing in mind, to teach kids to play jazz. And I used all the local musicians and one of the best tunes I thought to get the kids started to play would be a blues, and then we picked "C Jam Blues" because it's so repetitive, and the kids had these little instruments like a vibraharp, with two octaves they all had to play on. And we did in fact get kids to not only play this tune but to improvise on it. And we culminated with a concert with Duke, he came down and played with a small group for the kids in the school And it was one of the great experiences of my life. So at that time I thought that they really had done some good things and it was a shame that they couldn't follow through, like after we left the program just fell apart. I mean it broke my heart because we really had kids improvising with the Navy band, which was, what an experience that was, I'll never forget. Anyway, I guess I basically think that you can, if somebody is interested, you can point them in the right direction. I think kids have to be motivated. And I think if they really want to do it that's half the battle. And then they will investigate and listen and that's a part of it. But I have seen and done workshops and stage band clinics and things where you hear some of these kinds and you think oh these kids will never play. Next year the kid comes back, having listened to Bill Evans or somebody, and is playing away, and I'll never say never to anybody, because I think it takes wanting to do it, and motivation, and that's about it really.
