This was George Harrison's fourth night performing with Delaney & Bonnie, the husband and wife act then on a brief tour of the UK.
Harrison stayed on the tour for six dates, until it ended. They played two shows each night, in Bristol, Birmingham, Sheffield, Newcastle, Liverpool and Croydon.
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 Newcastle's City Hall with The Beatles on four occasions: 23 March 1963, 8 June 1963, 23 November 1963 and 4 December 1965.
