The recording sessions initially concluded in April, but unexpectedly resumed in June. Rieley had asked Brian about including "Surf's Up" on "Landlocked", and in early June, Brian suddenly gave approval for Carl and Rieley to finish the song. While on a drive to meet Mo Ostin, Brian said to Rieley: "Well, OK, if you're going to force me, I'll ... put 'Surf's Up' on the album." Rieley asked, "Are you really going to do it?" to which Brian repeated, "Well, if you're going to force me." According to Rieley: "We got into Warner Brothers and, with no coaxing at all, Brian said to Mo, 'I'm going to put 'Surf's Up' on the next album.' I think this was a great thing because it did provide a commitment on Brian's part and he became more active in the studio."
