I read where Jimmy Buffet was worth 1.3 billion at the time of his death. Of course it was him and a back-up band rather than big name musicians next to him.
McCartney is something like 1.2 billion. Ringo is about $500 million.
Russell Wilson, 5 year contract with the Broncos: $242 million.
Pretty good for a entertainer that NEVER had a number one single. I believe “Come Monday” was his biggest hit.
Jimmy Buffett built an entire industry around his “tropical rock” lifestyle. His actual record sales became very insignificant to his fortune.
