Chris Squire, the bass guitarist and co-founder of 1970s British progressive rock band Yes, has died at the age of 67, his bandmates have said.
Current Yes keyboardist Geoffrey Downes tweeted: "Utterly devastated beyond words to have to report the sad news of the passing of my dear friend, bandmate and inspiration Chris Squire."
Squire revealed in May he was suffering from a rare form of leukaemia.
The band said he died "peacefully" in Phoenix, Arizona, on Saturday night.
"It's with the heaviest of hearts and unbearable sadness that we must inform you of the passing of our dear friend and Yes co-founder, Chris Squire," said a statement on the band's official website.
