You're a Big Boy Now is a soundtrack album by the Lovin' Spoonful, released in 1967, containing music from the Francis Ford Coppola film of the same name. Composed entirely by Spoonful member John Sebastian, it contains several songs performed by the band, as well as instrumental music from the film score.
The songs "Darling Be Home Soon" and "You're a Big Boy Now" were released as singles on the Kama Sutra label. Although the album and title-track single were not popular, "Darling Be Home Soon" was a hit, reaching #15 on the U.S. charts and #8 on the Canadian charts, and inspiring cover versions by many other artists.
Music critic William Ruhlmann wrote of the album, "Most of the rest of the score consisted of instrumentals, many augmented by an uncredited orchestra, but Sebastian's title song was also impressive."[4]
