1. I am NOT trolling
2. I am NOT trying to stir the pot
3. I LOVE Phish...
4. ...and have since 1992

not that any of that means very much...i just want it to be clear that I am asking the following question out of sincere curiosity: how do we know that the 31st's Tweezer jam was NOT composed and rehearsed???...and, for god's sake, no, I don't mean note for note...I'm referring to each individual movement having been pre-outlined...for lack of a better example, kinda like Miles' s concept for Kind of Blue
