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

I can sort of see where you're coming from. I made a comment yesterday suggesting that one particular "movement" towards the end of the jam could possibly be something they've worked on for the new album & might have seeped out at an opportune moment. Actually, even if that's not the case, I hope they do use that "theme" to compose a new song. The riff/groove is so good at that point that I would just love to hear it played live again in some form, and as a new tune would be great, in my humble opinion.
