Description:  Butch Cassidy and the Sundance Kids was a 1973 Hanna-Barbera Saturday morning cartoon about a teen rock band who secretly worked as government-backed secret agents. The show was similar in format to Scooby-Doo and Josie and the Pussycats, featuring the band Butch Cassidy (lead singer), Merilee (tambourine), Stephanie (bass), and Wally (drums), along with Wally's dog, Elvis. Their missions were assigned by a supercomputer named Mr. Socrates, who had a violent allergy to dogs.

The Band: Butch Cassidy (lead vocals and guitar), Merilee (tambourine), Stephanie (bass guitar), and Wally (drums).

The Secret Life: They were government agents who solved mysteries and foiled criminals while on tour.

The Mission Control: A supercomputer named Mr. Socrates advised them, but was always driven haywire by Wally's dog, Elvis, who always found a way to sneak into the lair.

The Title: The show's title was a play on the 1969 film of the same name, but the cartoon was unrelated to the movie's characters. The series was also known as Butch Cassidy and was produced by Hanna-Barbera Productions.
