Blue Chip, Teacher's Pet, Sing Along, Big Ben, Gaucho, Bon Voyage, Volley, etc..., are themes that would be ripped on today.
I can't imagine Gary having a designer meeting and asking Steve, John or George who wants to design the next theme based on the giant clock in London.
I can't see Steve saying, "If John gets to do a clock theme, I get to do Central Park!"
I realize that it was a different time, but some of those themes really just make me scratch my head as why they were created in the first place.
