The first round of vocal overdubs were recorded later that day at Columbia Studios. Brian sang the lead vocal at this juncture, after which he mixed rough edits of the song on March 13 and 22. These early mixes featured a discarded saxophone solo in its bridge and a different, a capella ending. The ending was a fuller arrangement that included the voices of Marilyn, her sister Diane, and Byrds producer Terry Melcher. In Carl's recollection, "everybody got in on it. It was like 'Come on out here into the studio.' Brian would make up a little part. That was fun; we listened to it endlessly."
