|Frank Stallone is Sylvester Stallone's songwriting/singing brother. Harry Nilsson produced Frank's recording of "Case of You". It was during the "Case of You" session that Harry learned of John Lennon's death.
"A kid came running in the other side of the studio and he said 'John Lennon's just been shot. He's dead.' And it was like, 'what?' And everything just stopped for a minute. People just looked at each other and shook their heads. I went into the bathroom and put a wet towel on my face and said 'Jesus Christ, not him.'" -- Harry Nilsson (Source: 1992 Interview with Pete Fornatale https://youtu.be/ACLNhTmHgdY)
