'It’s The Great Pumpkin, Charlie Brown' features some of the most iconic tracks in pop culture, including the instantly recognizable “Linus and Lucy,” as well as the languid, lyrical “Great Pumpkin Waltz.” The music was recorded on October 4, 1966 at Desilu’s Gower Street Studio in Hollywood, California by Guaraldi (piano) and his longtime friends and trio sidemen — bassist Monty Budwig and drummer Colin Bailey — joined by Emanuel Klein (trumpet), John Gray (guitar) and Ronald Lang (woodwinds). The entire scoring process was overseen by composer, arranger and conductor John Scott Trotter, well known for a three-decade run as Bing Crosby’s music director and close friend.
