At the end of the night, the four Beatles and some of their guests overdubbed an extended humming sound to close the song – an idea that they later discarded. According to Beatles historian Mark Lewisohn, the tapes from this 10 February orchestral session reveal the guests breaking into loud applause following the second orchestral passage. Among the EMI staff attending the event, one recalled how Ron Richards, the Hollies' producer, was stunned by the music he had heard; in Lewisohn's description, Richards " with his head in his hands, saying 'I just can't believe it... I give up.'" Martin later offered his own opinion of the orchestral session: "part of me said 'We're being a bit self-indulgent here.' The other part of me said 'It's bloody "marvellous"!'"
