Lucky you! My 15 year old wouldn't be caught dead having my old fart band play our music from the olden days at one of his parties! He did recently tell me he had heard a couple of bands from my time that were better than the stuff I listen to, (Grateful Dead, Jefferson Airplane, The Band, etc.), and the asked me if I'd ever heard of Metallica or AC/DC! I think I blew him away when I told him that Metallica used to practice in a garage in El Cerrito just a few houses down from where my band, Norman Carburetor used to practice.
