Thanks everyone for these great comments! It was recommended to me privately that I consider revising the post or creating a new one describing a few more of the two-jam-segment versions since I only cover a few in the blog post above. But I'm proud of the way the post already punishes the reader into ruing the day he or she ever cared about whether there was only one, or more, jam segments of "Mike's Song," and I think I'd prefer not to make it more painful.

That said, for anyone who cares, here's one of my favorite 20+ minute versions broken down, 11/6/96 Knoxville:

2:48 First jam segment begins
9:55 Closing chords for first jam segment
10:13 Second jam begins (new track in PhishTracks)
{jam segues into "Swept Away" after 13 mins}
