Yes Bassist And Co-Founder Chris Squire Dies At 67

He announced last month that he had been diagnosed with leukemia.

Chris Squire, a founder of the legendary rock band Yes, and the only member of the band to have appeared on every album, passed away Saturday night (June 27), according to a statement posted on the band's Facebook page. He was 67 years old.

Just last month, Squire made public that he had been diagnosed with a rare form of leukemia, Acute Erythroid Leukemia. The time he took off touring to undergo treatment was the first time the band had toured without Squire since it was formed in 1968.

Geoffrey Downs, current keyboardist for the band, tweeted a remembrance of Squire this morning.

As part of Yes, Squire won a 1985 Grammy Award for Best Rock Instrumental Performance for "Cinema." He performed on 21 Yes albums, and released one solo album.
