Live versions so different they're like a new SP song

Can you think of any (excluding "Silverf*ck")?

I have two examples that are probably in most long-time fans' minds:

"Heavy Metal Machine" from 2007/2008 was so heavily reworked and incorporated so many classic rock teases that it's become a distinct and essential part of the discography for me.

Then of course there's "X.Y.U. Medley" which borrowed lyrics and guitar motifs from "X.Y.U." but also teased other songs, had live adlibs, and featured a totally different groove. The version on the Adore box set is definitive.

What else am I missing? (And "Silverf*ck" doesn't count. It was always an elastic song that included many jams and Pastichio nuggets)
