"Revolution" was performed in a higher key, B major, compared to the A major of "Revolution 1". The "shoo-bee-do-wop" backing vocals were omitted in the remake, and an instrumental break was added. "Revolution" was given a climactic ending, as opposed to the fade out of "Revolution 1". For this version, Lennon unequivocally sang "count me out". An electric piano overdub by Nicky Hopkins was added on 11 July, with final overdubs taking place on 13 July and mono mixing on 15 July.
