recorded to showcase Carl's guitar-playing, is the album's only instrumental track and the final surf instrumental released on any of their studio albums. It serves as a companion piece to "Denny's Drums" from Shut Down Volume 2. Musicologist Philip Lambert speculates that the track was based on "Can I Get a Witness", a recent hit for Marvin Gaye. Side two "Wendy" portrays a man's dejection after discovering that the woman whom he thought was his girlfriend was actually romantically involved with somebody else. Wilson, who later named his second-born child "Wendy", stated that the song was musically influenced by the Four Seasons. Leaf suggests that the song has "one of the most unusual introductions of any record from the rock era", making it "one of the most distinctive Beach Boys tracks ever." "Do You Remember?" is a celebration of 1950s rock 'n' roll performers such as Little Richard, Chuck Berry, and Elvis Presley.

During the filming of the 1995 documentary Brian Wilson: I Just Wasn't Made for These Times, director Don Was attempted to coax Wilson into discussing the unfinished album Smile. To achieve this, he approached Wilson by asking him
