The Beatles' Christmas Message: 1965

You know what was a really big deal in 1965? Well, besides, the band's second movie, Shea Stadium, and Rubber Soul, that is? "Yesterday," of course. The 1965 Christmas message--the last message to be more of a true message rather than a pantomime, which is what the later messages sort of evolved into-- features the Beatles gleefully lampooning Paul's masterpiece several times, which is a large part of what makes it great.

Also funny: the band launching into the first bit of "Just the Same Old Song," until George realizes there's a copyright issue if they continue.
