Harrison performed on five of the tour's six dates, playing two shows each night. He appeared in Bristol, Birmingham, Sheffield, Liverpool and Croydon. He didn't perform at the Newcastle shows on 5 December, instead briefly leaving the tour to visit his unwell mother.
Several of the shows were also recorded for possible album release - the result was 1970's Delaney & Bonnie & Friends On Tour With Eric Clapton. Harrison was credited as "Mysterioso".
Harrison had previously performed at Birmingham's Town Hall on 4 June 1963, during The Beatles' tour with Roy Orbison.
