Jeremy Clyde was at the Chicago FanFest last year, and when I got his autograph, I asked him about being on the Dick Van Dyke Show. He said it was a wonderful experience, everyone was fantastic, a great group of people to work with, and very professional, that they had a lot of fun and laughter on the set. He said he ad-libbed the line "It's a chair" (you'll hear it in the show), and Dick loved that and wanted to keep it in. As a bit of trivia, Jeremy is a grandson of the 7th Duke of Wellington, and was an altar boy at Queen Elizabeth II's coronation at Westminster Abbey in 1953. He said he was a free spirit, and enjoyed music and acting more than being in the circles he grew up in, so decided to make his living as a musician. In addition to his music, he also acts in film and TV.
There was a story I heard him tell someone else about how he packed his guitar over his shoulder one day and went to Peter Asher's house where Paul was living at the time... that the three of them were jamming while sitting on the ledge high outside the windows of the third floor of the house, with their legs dangling, and didn't seem to care that any of them could have fallen to their death... they were just having too much of a good time playing their music! Too bad there wasn't a film made of that, like the rooftop concert, would have been great to watch!
