that the session "went very badly". That evening, Wilson had been filmed at Columbia Studio singing and performing "Surf's Up" on piano for use in David Oppenheim's CBS-commissioned documentary Inside Pop: The Rock Revolution. According to Siegel, Wilson and Oppenheim were dissatisfied with what they had filmed, and decided to reshoot the sequence at Wilson's home two days later, on December 17. His performance that day, executed in one take with a candelabrum placed on his grand piano, was captured by three film cameras and deemed satisfactory for use in the documentary. The lost sessions from January 1967 reportedly involved additional instrumental tracking, including a 16-piece string and horn section that was overdubbed onto a bounced tape of the backing track from December 15. A fully-developed recording of the song's second movement has never been found. In 2004, Darian Sahanaja said that a tape for the instrumental tracking of the section was rumored to exist somewhere, while Mark Linett stated, "If it does exist, we haven't found it." Asked decades after the fact, Wilson responded that he did not think that he ever recorded it. In 2011, Linett commented, "It’s interesting because there’s a session sheet indicating that the second half of 'Surf’s Up' – the backing track was recorded. But there's never been any taped evidence of it, and obviously there was no taped evidence when the Beach Boys went to finish it in the Seventies. And nobody, including Brian, can confirm that it ever happened. So it may have been a session that was mislabeled, or a session that got canceled."

Brian's segment in the documentary featured him singing "Surf's Up" at his piano without any interview footage or references to Smile. Oppenheim declared through voice-over that the song was "poetic, beautiful in its obscurity" and "one aspect of new things happening in pop music today. As such, it is a symbol of the change many of these young musicians see in our future." He further described Wilson as "one of today's most important pop musicians." According to Badman, Wilson's segment aroused "great expectations" for Smile, while journalist Nick Kent wrote that Wilson was "freaked out" and "broke down" over the praise he was afforded in the documentary. After Smile was scrapped, Wilson neglected
