The London concerts were the first time he had appeared in that city since performing with Them, six years earlier. The two concerts at the Rainbow Theatre in London were referred to as "the rock event of the year" by critics according to Ritchie Yorke in his biography. The 24 July 1973 London Rainbow concert was the first BBC simulcast broadcast simultaneously on BBC 2 television and Radio 2 stereo so that viewers with strategically sited loudspeakers could enjoy "stereo TV". The broadcast took place on 27 May 1974.
