On the subject of Sabatoge, I think you guys are confusing yer genres. It's not prog rock or classical, it's not supposed to be perfectly played. It's supposed to rock yer ass off. Did it? Then mission accomplished. I've seen video of the Beastie Boys playing that tune and they focused more on jumping around the stage and pumping up the energy than hitting every note. Money Mark was doing handstands on his keyboards. It's not really the most serious musical endeavor.
That said, I have seen some well played versions, the two times it was played in 98 are tight.
