The Who lead singer Roger Daltrey described Mercury as "the best virtuoso rock 'n' roll singer of all time. He could sing anything in any style. He could change his style from line to line and, God, that's an art. And he was brilliant at it." Discussing what type of person he wanted to play the lead role in his musical "Jesus Christ Superstar", Andrew Lloyd Webber said: "He has to be of enormous charisma, but he also has to be a genuine, genuine rock tenor. That's what it is. Really think Freddie Mercury, I mean that's the kind of range we're talking about."
