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."
