In 1962, pianist Vince Guaraldi created that rare thing, a hit jazz instrumental, “Cast Your Fate to the Wind”, which reached #22 on the Billboard chart. The recording won a 1963 Grammy for Best Original Jazz Composition. A few years later, Guaraldi enshrined himself in American popular culture as the composer of the songs for the Peanuts TV specials.
On their first date, lyricist Carel Werber went with her future husband Frank, then manager for the Kingston Trio, to a club in Sausalito, where Guaraldi played the song for her. She loved it, and wrote the lyrics during trips over the Golden Gate Bridge.
Singer Shelby Flint had her own Billboard #22 hit, “Angel on My Shoulder”, which she wrote, in 1962. Her vocal version of Guaraldi’s song was released in 1966, reaching #61 on the Billboard charts.
The song starts in Db major, with a modulation to D in the instrumental section at 0:51, closing with another half-step shift up at 1:14. The verse then resumes in D-flat.
