I don't think he was tired of it or they wouldn't have played it at all. I don't think there's any Zep songs Jimmy was tired of actually. Some songs besides Heartbreaker and Communication Breakdown would have been welcome. Maybe re-introducing The Wanton Song as an encore could have worked. It's a shame they dropped The Ocean after 1973, considering how often people in the crowd would shout for it.
It's my favorite of all the '75 shows available on soundboard. I think it's an absolutely fantastic show from beginning almost to the end. Very creative playing and a high-energy performance from the band. It is a shame the Jimmy just completely lost it just in time for Heartbreaker though.
I remember how loud and excited the crowds got just before the Moby Dick outro on both nights. My guess is either there were a lot of drummers in the audience or people were excited that the damn things were finally gonna be over.
I've only heard bits of the audience tapes for 5/26 and 5/28 but what I remember from all four, the audiences were very into it, especially the first night. The 26th starts off good but over the top fucked it all up.

EDIT: On No Quarter now. Really a great performance all around. Very creative playing from Jimmy. (I'm not joking.)
Am I crazy or does the picture quality seem to improve a bit during the big guitar solo then go back down to what it was before after it's over?
