This was George Harrison's third 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 Sheffield's City Hall with The Beatles on five occasions: 2 March 1963, 16 March 1963, 25 May 1963, 2 November 1963 and 9 November 1964.
