Not unexpected but still hate to hear this. Saw him for the last of five times a little over a year ago. He was frail and the voice was gone, but the crowd loved him anyway.
A giant among prolific songwriters. Talent and drive that made everything else in his life take a back seat until he was well up in age and gained a different perspective that many of us attain with age and hard experience.
Like I said, not unexpected, but he's one I shall miss greatly. Thankfully his body of work will survive him and be enjoyed for a long time to come.
