Phil Spector had planned to produce a session with John Lennon joining Cher to sing "A Love Like Yours" which Spector had originally recorded with Ike and Tina Turner. But when Spector arrived at the studio, he learned that Lennon was "incapacitated." But Harry Nilsson was there. When Cher walked in, Nilsson began singing and exclaimed "Nilsson and Cher! Number one worldwide!" When asked a couple years later about the recording, Harry responded "Have you heard it? How is it?" [1]
