Re: Jon "Bermuda" Schwartz here!
The song was actually 11 minutes, but at that tempo (190 I think?) it may as well have been 11 hours! It's a workout, one reason why we never normally performed it live.
I think most of it was one take, it's pretty straight ahead part but incessant. I think the ending was re-recorded a week later, but the rest of the song was probably one take.
