The only Zappa tune I ever covered was "Broken Hearts are for 4$$h@les". The only challenge of any kind were the harmonies. Well, that and getting through it without laughing.That's awesome! My dream is to be in a jam band that can cover a few of the hard / awesome Zappa epics like Pygmie Twilight and Florentine Pogen. Also a few off the first three Phish albums like You Enjoy Myself and Reba. Hard to find those musicians. You also convinced me it might be hard to find that musician within myself to keep up! I can read but I can't sight read at that speed. Worth it to memorize a few good ones.
