This is very sad news, although I was aware that he had been ill for some time.
Last time I saw him was at Swanage - about 3 or 4 years ago. His playing as usual was sensational, not putting a foot wrong and as BillF says - truly world class.
Not only was he a world-class saxophonist but he was also world-class in the area of model aeronautics, I believe.
RIP - irreplaceable on our local scene.
