NEW YORK — Chris Squire, the bassist and co-founder of the progressive rock band Yes who recently announced he had leukemia, has died, according to a statement from his band members on Sunday. He was 67.

The band posted a statement on its Facebook page saying Squire “peacefully passed away” Saturday in Phoenix, where he lived.

Squire announced last month that he had acute erythroid leukemia, a rare form of acute myeloid leukemia. He was receiving treatment before he died.

Squire was born on March 4, 1948, in London. He co-founded the band with its former lead singer, Jon Anderson, and the group released its self-titled debut album in 1969. Squire was the only member to play on all of Yes’ albums.

The Grammy-winning band’s hits include “Roundabout” and “Owner of a Lonely Heart,” which became a No. 1 hit on the Billboard pop charts in the 1980s.

The group will launch a U.S. tour with Toto in August, when Billy Sherwood will fill in for Squire.
