Starr and the other Beatles performed their song "Ticket to Ride" on the 13 May 1965 instalment of Top of the Pops, introduced by Jimmy Savile.

(TV: The Chase) According to one account which claimed that the Visualiser was a hoax, the people seen on the Visualiser were not the genuine historical figures but human slaves of the Pursuer-Daleks who were made to re-enact the event as a deception for the Doctor and his companions.

Unlike the other potential Beatles, however, he was not enlisted in the British Army as part of national service due to health problems. (AUDIO: 1963: Fanfare for the Common Men)
