Were the drums set up in the stairwell or was the stairwell used as a chamber with a speaker microphone set up?
I believe that the drums were set up in the foyer - at the base of the stairs. This was a mansion they were at..
Bonham down in the foyer and the mics were up the stairwell. I don’t recall exactly how many feet or floors up they were placed. I’m sure there’s video or interviews with John’s or Nevison about the details.
