Not an unusual opening at all, otherwise. He's very reptitive on a rather b.s. theme, imo, for the first minute or thereabouts, before taking off and soloing more profoundly. Not a 'tease' of the main simple lick, but what Trey plays is definitely similar. This post-tramps jam is fairly chaotic, as they ususally were in this period. I really can't hear the FAHT well enough to comment.
Fish comes in shortly.
Page complements it well fairly soon. Well, Page sounds great. In the wrong key, but Trey starts playing the Weekapaug chords. And the Mike's Song is pretty powerful and weird, too. Total screwing around.
