From his FB page:
It is with great sadness that we, Jack’s family, announce the passing of our beloved Jack: husband, father, granddad, and all round legend. The world of music will be a poorer place without him, but he lives on in his music and forever in our hearts.
I said he didn't look well in the Silver Rails interviews, and also said that album sounded like he was giving everything he had left. A sad day. He was an inspiration to so many of us.
He may have made his name in Cream, but this is the song that I will always think of personifying him best.
