Coppola commissioned Sebastian to write music for the film, and for one scene wanted a song with a similar mood and tempo to "Monday, Monday" by the Mamas and the Papas. Sebastian said that he wrote the song as "pleas for a partner to spend a few minutes talking before leaving.... [but] you never knew if the other person was actually there listening or was already gone". Coppola approved the song, and it was recorded by the band but with session musician Billy LaVorgna rather than Joe Butler on drums. The arrangement was by Artie Schroeck. After the recording was completed and the musicians left, the producer, Erik Jacobsen, discovered that an engineer had mistakenly erased Sebastian's vocal track, so he had to re-record it the next day. Sebastian said: "What you hear on the record is me, a half hour after learning that my original vocal track had been erased. You can even hear my voice quiver a little at the end. That was me thinking about the vocal we lost and wanting to kill someone."[4] It has been described as "...one of the most heartfelt songs about being away from a loved one, written from the point of view of a musician on the road writing a letter."[5]
Billboard described the song as a "medium-paced rock ballad given that 'extra special' Lovin' Spoonful treatment" and should be a "smash" on the Billboard Hot 100.[6] The critic Richard Goldstein, one of the earliest champions of the Spoonful,[7] criticized the song as the band's first disappointing single.[8] In his review for The Village Voice, he disparaged the song as a tribute to Bob Dylan which "lacks the master's raunchiness".[8]The Beatles regularly praised the Spoonful in interviews,[9] but when Paul McCartney reviewed the latest singles for Melody Maker in February 1967,[10] he criticized "Darling Be Home Soon" for its instrumentation, which he thought "very ordinary" and "corny".[11] While complementing Sebastian's vocal, McCartney hypothesized that the film studio pressured the band to keep the song's arrangement "flimsy".[11]
