Okay, so I have two copies of Teen Town. I keep one copy at home for practice and one in my locker at college for rehearsals. Upon closer inspection of the music I use at rehearsals, the second page basslines were different in rhythm and notes. I compared this sheet music to what Jaco plays, and it's different. The result is that I am playing it correctly (I learned the basslines from the copy of music I have at home, which is correct), but the other bassist in the band (we're doing a bass duo thing -- I'm actually the keyboardist) learned it from the school copy. And we're supposed to play those lines in unison. On one hand I don't want to have to relearn those lines, and on the other hand, I don't want to piss him off by asking him to relearn his. Uh oh. Maybe we should take turns playing the lines or something? Moral of the story: pay special attention to the sheet music you're using for Teen Town.
