"Snoopy vs. the Red Baron" is a novelty song written by Phil Gernhard and Dick Holler and recorded in 1966 by the Florida-based pop group The Royal Guardsmen.

As Holler said later, "We went down to Cosimo’s in New Orleans and recorded it, and spent all day putting in airplane sounds and machine gun bullets and took it around to every major label.

"[9] Four years later, producer Phil Gernhard saw that the comic strip, Peanuts by Charles Schulz, was featuring a recurring storyline of Snoopy imagining himself in the role of a World War I airman (and his doghouse a Sopwith Camel fighter plane), fighting the Red Baron.

[10] The record was released approximately one year after the first comic strip featuring Snoopy fighting the Red Baron appeared on Sunday October 10, 1965.

Schulz and United Features Syndicate sued the Royal Guardsmen for using the name Snoopy without permission or an advertising license.

A rare promotional record (only 1,000 were pressed, labelled "Omnimedia") for the advertising arm of Charles Fuller Productions included the removed lyrics "Hang on Snoopy".

The song was featured as a cover version on a children's album of the same name in the early 1970s by The Peter Pan Pop Band & Singers.

In 1973, a group named The Hotshots reached number 4 in the UK Singles Chart with their cover version of the song, performed in a ska style.
