That evening, in a four-hour session in Studio Two, each of the three present Beatles recorded a demo of a newly written song. Harrison recorded "You Know What to Do"; John Lennon did "No Reply", which eventually ended up as the opening track of their next album, "Beatles for Sale"; and Paul McCartney did "It's for You", a song which was written specifically for Cilla Black to sing. The tape of the session was subsequently misfiled, but was rediscovered in 1993.
