Chris Squire, the founding member and bass guitarist of UK prog rock outfit Yes. The 67-year-old was recently diagnosed with Acute Erythroid Leukemia, a rare form of Acute Myeloid Leukemia

Yes announced the news of Squire’s passing on Facebook, writing, “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. Chris peacefully passed away last night in Phoenix Arizona, in the arms of his loving wife Scotty.”



“For the entirety of Yes’ existence, Chris was the band’s linchpin and, in so many ways, the glue that held it together over all these years,” the statement continues. “Because of his phenomenal bass-playing prowess, Chris influenced countless bassists around the world, including many of today’s well-known artists. Chris was also a fantastic songwriter, having written and co-written much of Yes’ most endearing music, as well as his solo album, Fish Out of Water.”

Squire co-founded Yes in 1968 alongside singer Jon Anderson, guitarist Peter Banks, keyboardist Tony Kaye, and drummer Bill Bruford. He would remain the lone constant member of the band, however, appearing on every one of their 21 studio albums. Additionally, he co-wrote some of Yes’ most notable songs, including “I’ve Seen All Good People”, “Starship Trooper”, “Owner of a Lonely Heart”, “Yours Is No Disgrace”, and “Heart of the Sunrise”.

A more complete obituary will be posted later today.
