It was announced on Twitter this morning. Fellow ASIA bandmate Geoff Downes shared the bad news:
John Wetton has died. A co-founding member of two fantastic super-groups, King Crimson and Asia, had been battling Colon Cancer. He was 67. Although Asia remains active with original members Carl Palmer and Geoff Downes, Wetton had been ill and was unable to take part.
Dear All, I am sorry to be the bearer of the very sad news that my dearest friend, bandmate and co-writer, John Wetton has passed away.— Geoffrey Downes (@asiageoff) January 31, 2017
