John Eastman, the former brother-in-law of Paul McCartney, died at age 83 of pancreatic cancer, the former Beatle announced on social media on Thursday.
“My dear brother-in-law, John Eastman, has passed away. Having known each other for over 50 years it is an extremely sad time for me, and our families,” McCartney wrote on Instagram alongside a photo of the two.
Eastman was the brother of Paul’s late wife Linda Eastman McCartney, who died of breast cancer in 1998.
“John was a great man. One of the nicest and smartest people I have had the good luck to have known in my life.
