 DATE: When the bass player visits Disneyland he rides in a  Matterhorn car. The Matterhorn cars in the 1960s were single  bobsleds, not two tandem bobsleds as shown in the film. They didnt  run tandem until the ride was updated in 1978. Also, when he poses  for a photograph with Mickey Mouse, Mickey is wearing a 1990s  costume and definitely not a 1960s
