I'm sometimes behind on things with so much good happening in my life, but has rehearsal been discussed already? Is it listed as a different name?

A quick google search points to this release:

https://www.discogs.com/P.../10471339

CD 3, Tracks 14/15.

Is this what you mean?

I just came across Barts thread on this from 2017

.
