Spinetti gained international fame during the 1960s due to his association with the Beatles. He appeared in the first three Beatles films: "A Hard Day's Night" (1964), "Help!" (1965), and "Magical Mystery Tour" (1967). He also appeared on the Beatles' 1967 Christmas recording, released to members of their fan club. The best explanation for this long-running collaboration and friendship might have been provided by George Harrison, who told Spinetti, "You've got to be in all our films ... if you're not in them me Mum won't come and see them – because she fancies you." But Harrison also later told him, "You've got a lovely karma, Vic." Paul McCartney once described Spinetti as "the man who makes clouds disappear". Spinetti made a small appearance in the promotional video for McCartney's song "London Town" from the 1978 album of the same name. Spinetti's July 2010 performance of the song "Ob-La-Di, Ob-La-Da", at the Festival Theatre, Malvern in Worcestershire, was available on "The Beatles Complete on Ukulele" podcast.
