First, I would definitely recommend Craig's book. It has amazing photos and interviews, but my favorite section is the intensive record on all of the Airplane's performances, which include all of the songs they played, and special notes, such as when it was first performed, etc...
Well, something interesting. I had a little trouble finding it in Craig's book. In the liner notes that came with the CD, it said it was performed in November, but it should probably read October 26, 1968. Fat Angel was the opening number that night, and Bless Its Pointed Little Head was the first live album.
However, I couldn't find any information on who was playing what.
As for the studio version of the song, I am a little skeptical. They often performed Other Side of This Life live, but to my knowledge, was never done as a "studio version".
