Album producer Max Norman stated in 2007 that due to a limited budget, he had Osbourne and the band perform an entire extra show with no audience in the afternoon of either the 26th or 27 September. Norman recorded that performance in the event that the actual live shows were not of suitable quality for release. "At least we've got a choice and we'll have more material to draw from", he said of this decision. According to Norman, the finished album features three songs from that performance with crowd noise later added in post-production. Though Norman did not specifically identify which tracks he was referring to, he said "If you got nothing to do for a couple of days you could just lie there and listen to them in the headphones and figure out which songs had the real audience and which ones didn't." Soundboard recordings of both performances, which exist as bootleg recordings, seem to prove that all tracks appearing on the album with the exception of "Sabbath Bloody Sabbath" were taken from the 27 September show. "Sabbath Bloody Sabbath" was not played at either of the Ritz concerts and the recorded version included on "Speak of the Devil" is believed to have come from the afternoon recording referenced by Norman.
