Doctor Who meets the Beatles, 1965

The Beatles had a guest appearance on Doctor Who in 1965 -- singing "Ticket to Ride." Afterwards, a traveller from the future remarks that she's heard of the Beatles, having visited their memorial in Liverpool, but that she didn't realize that the Beatles also performed "classical music." This is black-and-white Doctor Who comedy gold. Link (via Making Light)

Update: David sez, "The original recording of that particular Beatles performance has been lost along with a lot of the BBC library which was tragically thrown out in a great video tape purge in the 1970s. That Doctor Who footage is now the only visual record of that performance."
