The Beatles, being the well-mannered fellows that they were, would send thank you notes to the people that helped them out on the tour, often with a small gift. I wonder if bands nowadays still do this sort of thing? The letter here was sent to Larry Kane, and while it could have been a form letter, it was obviously signed by the Beatles and I love how George sends a note to say hi to Sgt. Buddy (he really must have made an impression of the Beatles!)
