Rock bands including Kiss and Pearl Jam have paid tribute to heavy metal singer Ronnie James Dio, who died from cancer at the weekend, aged 67.
On Monday, at a gig in Switzerland, Kiss guitarist Paul Stanley led fans in a chant of former Black Sabbath singer Dio's name.
And grunge stars Pearl Jam performed a riff from one of Dio's songs, Heaven and Hell at a gig in the US.
Ozzy Osbourne called Dio one of metal's "greatest voices".
Dio replaced Osbourne as the Black Sabbath singer in 1980. In a statement, Osbourne said: "My heart goes out to his family and to his many fans. ... Love and respect."
Sabbath bassist Terry 'Geezer' Butler visited Dio in hospital and said of the day: "In the evening, the chaplain came, and we all gathered around Ronnie's bed and prayed.
"At 11pm, most of us left, leaving Wendy [Ronnie's wife] her privacy to say her last farewell. The devastation was palpable."
In another statement, rock legends Kiss said: "In addition to his powerhouse vocal ability, Ronnie was a true gentleman who always emanated great warmth and friendship to us and everyone around him."
At Monday night's gig in Geneva, the band led fans in the chant: "Ronnie! Ronnie! Ronnie! Ronnie! We love you and we miss you!"
Guitarist Doug Aldrich, who played with the vocalist, said: "I was blessed to share some music with him, but mostly, I am thankful for his friendship," describing him as a "good-hearted, caring man".
Nearly 45,000 people have left tributes to Dio on Facebook.
