Rod Stewart has said he is "devastated" after learning of the death of his former Faces bandmate Ian McLagan, who also performed and recorded with the Rolling Stones.
Keyboard player McLagan died after suffering a stroke in Austin, Texas, as he was preparing to begin a North American tour.
The 69-year-old musician, who was born in Isleworth, Middlesex, had been a member of Small Faces in the 1960s, which evolved into the Faces when singer Rod and guitarist Ronnie Wood joined in 1969.
There had been talk of members of the group reuniting in coming years, although Simply Red star Mick Hucknall stood in as singer when the group last performed a series of shows.
Rod said: "I'm absolutely devastated. Ian McLagan embodied the true spirit of the Faces.
"Last night I was at a charity do, Mick Hucknall was singing I'd Rather Go Blind, and Ron Wood texted to say Ian had passed. It was as if his spirit was in the room. I'll miss you mate."
McLagan worked with his old pal Wood again by teaming up with the Rolling Stones, playing on the band's 1978 album Some Girls. He provided the organ solo on the hit Miss You, and was inducted into the Rock and Roll Hall of Fame two years ago.
McLagan had also worked with Billy Bragg, who paid tribute with a message on Twitter which said: "I have lost a dear friend and British rock has lost one of its greatest players."
