[7] Following the passing of producer Lee Mendelson in December 2019, his children undertook an extensive search of archival materials in hopes of locating original music score recordings from the Peanuts television specials.

These recordings, long believed to be lost, comprised not only all of Guaraldi's music cues but also the arrangements by John Scott Trotter, including multiple alternate takes.

[1] The recording sessions for the It Was a Short Summer, Charlie Brown soundtrack, conducted on September 11 and 12, 1969, reflect Vince Guaraldi’s collaborative approach and the integration of a larger ensemble to create a more dynamic and varied score.

Notable participants included trumpeters Conti and Pete Candoli, trombonist Frank Rosolino, woodwind players William Hood and Peter Christlieb, guitarist Herb Ellis, bassist Monty Budwig, drummer Jack Sperling, and percussionist Victor Feldman.

Additional "Camp Green" and "Summer Night Blue" vinyl color variants were also issued as Record Store Day Indie exclusives.

This piece, among others, demonstrates refined musicality through intricate flute solos and rhythmic interplay from the expanded ensemble, offering a fresh approach to Guaraldi’s classic themes.

In addition, the reprise of "You’re In Love, Charlie Brown" "catches nuances of the characters", featuring compelling solos from Feldman on vibraphone, Herb Ellis on guitar, and Guaraldi himself.
