An expanded soundtrack from a Charlie Brown Thanksgiving special is released Friday.

A Charlie Brown Thanksgiving is launched to commemorate 50 years of the Charlie Brown special, which aired in November 1973.

The restored, remixed and remastered album by the late jazz composer and keyboardist Vince Guaraldi features 21 tracks, nearly half of which are previously unreleased.

As many fans of the comic know, Guaraldi’s tunes emit the warm glow of a fireplace during the holidays, making them ideal background music.

Guaraldi is accompanied by Seward McCain on electric bass, Mike Clark on drums, Tom Harrell on trumpet and Chuck Bennett on trombone, and the tunes are explored by the band in various configurations, including re-recordings.

There are new versions of familiar tunes Thanksgiving Theme and Linus and Lucy. Five tracks titled Thanksgiving Interlude are included, including a version used in the series which was the 17th and final take.
