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.'
