Deep Purple (29. januar 2022). «Blind Man California». The Highway Star. Besøkt 29. januar 2022. «There was a gig in April 1972 when Ritchie fell ill and Randy California was called upon to save the day. A bootleg recording of When a blind man cries from that gig (April 6, 1972 in Quebec City) has been posted on Youtube. The quality is about what you’d expect from an audience recording of that era, so don’t complain.»
