Quite remarkable really...
I looked this up earlier:
https://en.wikipedia.org/wiki/Chris_Squire
Christopher Russell Edward Squire (4 March 1948 – 27 June 2015) was an English musician, songwriter and singer, best known as the bassist and backing vocalist for the progressive rock band Yes.
He was the only member to appear on each of their 21 studio albums, released from 1969 to 2014.
He was widely regarded as the dominant bass guitarist among the early seventies British progressive rock bands, influencing peers and later generations of bassists with his incisive sound and elaborately contoured, melodic bass lines. His name was also associated with his trademark instrument, the Rickenbacker 4001 bass. From 1991 to 2000, Rickenbacker produced a limited edition signature model bass in his name, the 4001CS. He released one solo album, Fish Out of Water, in 1975.
In May 2015, Squire announced a hiatus from Yes after he was diagnosed with acute erythroid leukemia. Squire died on 27 June at his home in Phoenix, Arizona.
The band's first show of their tour with Toto on 7 August 2015 will mark the first Yes concert performed without Squire.
