Paul McCartney had the original idea for "Magical Mystery Tour", coming back from the Monterey Pop Festival in California, during the summer of 1967. He drew a clock face on a paper plate, and filled it with parts of the show he imagined. McCartney based the idea on Ken Kesey's Merry Pranksters, who travelled the United States in a bus, and also "", which were low-budget weekend vacation trips taken in England.
