The Musical is the 31st prime-time animated TV special based on characters from the Charles M. Schulz comic strip Peanuts.

[1] This is one of the two musicals in the Peanuts franchise where Snoopy has a speaking voice which only viewers can hear; the other is 1985's You're a Good Man, Charlie Brown.

Each vignette has a song that involves various members of the gang (Consisting of Charlie Brown, Lucy, Linus, Sally, Peppermint Patty, Woodstock, and Snoopy) Having adapted the musical You're a Good Man, Charlie Brown three years prior, Charles Schulz once again opted to adapt the other musical with the Peanuts gang.

Schulz had recently utilized many comic strips for The Charlie Brown and Snoopy Show.

The idea of Lucy mistaking a potato chip for a butterfly was borrowed from 1969's It Was a Short Summer, Charlie Brown.
