Theater

The characters first appeared in live stage production in 1967 with the musical You're a Good Man, Charlie Brown, scored by Clark Gesner. It is a collection of musical sketches, where the characters explore their identities and discover the feelings they have for each other. The play was performed off-broadway, as well as later being performed as a live telecast on NBC. The play continued to have other professional performances, in the London West End, and later a Broadway revival, while also being a popular choice of musical by amateur theater groups such as schools.

A second musical premiered in 1975, Snoopy! The Musical, scored by Larry Grossman with lyrics by Hal Hackady. A sequel to You're a Good Man, Charlie Brown, Snoopy! is also a collection of musical sketches, though focused on Snoopy. It was first performed in San Francisco, and eventually off-Broadway for 152 performances.

You're a Good Man, Charlie Brown and Snoopy!!! The Musical were both further adapted as animated television specials, respectively, in 1985 and in 1988. Going in the opposite direction from animation to live production, is the 2016 A Charlie Brown Christmas, based on the animated television special of the same name. It is considered a generally faithful readaptation, although it features the additional characters Woodstock and Peppermint Patty who did not exist in the strip when the original was made.
