The costume design is by David Graden, with lighting by Ken Billington, orchestrations and vocals by Laurence J. Blank, produced by John Anderson, and choreography by Marc Breaux.

The musical was first produced legitimately in Canada by the Toronto Civic Light Opera Company in January 1983.

The musical ran at the West End Duchess Theatre, opening September 20, 1983[4] and starred Teddy Kempner as Snoopy.

[6] It was directed by Joseph Pitcher and featured Stephen Carlile as Snoopy and Neil Gordon-Taylor as Charlie Brown.

The musical ran at the New Players Theatre in London, in July 2004, with several cast members from the Jermyn Street production and again directed by Whitelaw, the original director.

Directed by Greg Gesch, starring Jack Webster as Snoopy, Patrick Phillips as Charlie Brown and Zoe Bertram as Lucy.

Grossman was directly involved with this production: besides revising the book and adding or removing songs, Grossman collaborated with Andrew Lippa (who had previously contributed new music to the 1999 Broadway revival of You're a Good Man, Charlie Brown) on the new song "Husband Material".

[10] The musical ran at the Artscape Arena in Cape Town, South Africa in February 2018, starring Jaydon Farao in the title role of Snoopy.

Peppermint Patty has similar problems with love, wishing that she could be prettier to impress Charlie Brown ("Hurry Up, Face").

In school, the group hopes that the teacher will not call on them to answer a question about the famous poet Edgar Allan Poe.

Later, Peppermint Patty expresses her love for Charlie Brown ("Poor Sweet Baby"), but soon says that "it'll never happen" out of embarrassment.

The musical was re-released on CD in 1991, while on digital in 2000, with a strange glitch making all the songs in caps lock.

In 2018, in the collection Broadway to West End highlights from the original cast album were released, excluding "Overture", "Woodstock's Theme", "Hurry Up, Face", "Mother's Day", "The Vigil", "Dime a Dozen", "When Do the Good Things Start?

Clay was particularly miffed at the lead character's attenuated appearances: "rather than hoof himself dog-tired in the service of art, [Snoopy] grants his presence judiciously, particularly in the show's wearyingly jejune first act — the low point of which comes when Snoopy’s canary chum Woodstock, played by Cathy Cahn, turns out to be a mime (perhaps the cat has her tongue).

The book, which is credited to three individual writers as well as a task force called 'Charles M. Schulz Creative Associates' is a pastepot of Peanuts dialogue that wanders into various other neighborhoods in order to accommodate the score.

"[12] In the 1983 West End production The Guardian reviewed "The astringency of the jokes is belied by Hal Hackady's lyrics which place great stress on the American success ethic...

This innocent-looking revue certainly makes its point that the child is father of the wisecracking man; but I still can't help feeling that brevity is the soul of strip".

The musical retains the fast, sharp comic appeal and instantly recognisable characterisations of the line-drawing originals, but also irresistibly brings it to human form by buoying up its snapshot scenes with the tuneful ease of the light, bright melodies of composer Larry Grossman's settings to Hal Hackaday's apt, witty lyrics.
