O Tannenbaum
Guaraldi composed most of the music, though he included versions of traditional carols such as "O Tannenbaum". He recorded some of the score at Whitney Studio in Glendale, California, then re-recorded some of it at Fantasy Records Studios in San Francisco with a children's choir from St. Paul's Episcopal Church in nearby San Rafael. The sessions ran late into the night, with the children rewarded with ice cream afterward.
