The Who played a special "thank you" concert for the extras who worked in the Tommy movie. It was a "closed concert" and by all accounts the relaxed atmosphere inspired the band to play as well as they ever had. The general public weren't admitted, though a 'sold out' notice appeared in Melody Maker on May 11, 1974. During 'Bell Boy', the band got so out of time with the synthesiser backing that Pete ordered everyone to stop, had Bob Pridden rewind the tape, and the song was begun again. This was probably the worst experience the band had with the difficult Quadrophenia backing tapes but, since the show wasn't before a paying audience, it didn't seem to matter so much. The band started again in good humour, and Bob Pridden probably breathed a sigh of relief!
