 John Lennon (qv) and Paul McCartney (qv) actually did spend 24  April 1976 together as portrayed in the movie, but Yoko Ono (qv)  and Linda McCartney (qv) were also present. It was the last time  they met. They got along so well that Paul returned the next day to  see John. John would not let him in, saying, as he does in the  movie, "You cant just be dropping by like its the good old days."
