As it took me some time to decide on the holiday theme, I'm kicking off this new feature rather late on December 1. So we'll start with a relatively simple question.
Vince Guaraldi Trio's "Linus and Lucy" had its television debut on the very first animated Peanuts special: A Charlie Brown Christmas (1965). The song has since been a part of just about every Peanuts television show (and a whole host of other Peanuts-related media appearances). However, the tune was not composed for A Charlie Brown Christmas.
So, what was the project for which Vince Guaraldi originally wrote and recorded "Linus and Lucy"? Feel free to submit your answer in the comments!
