Hmm. Where would rock have gone without this track? To think this was recorded in one take, too. They must have been a helluva jam band. Too bad I was not even a teenager when this arrived. Well, maybe it was a good thing I wasn't over 18... the Psycehdelic scene probably would have been a heavy draw (pun intended).
I thought the live version was better, although there was an unfortunate edit (and an obvious one - the tempo changes abruptly) to fit it on an LP side. I wonder if there's an unedited version around anywhere.
