The song did not appear to have lyrics or a title at this juncture, and Wilson can be heard calling the song "Oh Yeah" and "You're Grass and I'm a Power Mower". In his 2016 memoir, Wilson remembered: "When we got into the studio with Chuck, he said that he wanted Carl's twelve-string guitar in the intro to sound more direct. I didn’t know what that meant. 'Can he play it in the booth?' Chuck said. I had never thought about that before, but it seemed like a good idea. Carl was standing next to me in the booth and all the other musicians were out in the studio. I conducted it like an orchestra." According to biographer Peter Ames Carlin, Wilson's father Murry urged Brian to eliminate the orchestral prelude, as he felt that it made the song excessively complex.
