LONDON -- Impresario Robert Stigwood, who managed the Bee Gees and produced 1970s blockbusters "Grease" and "Saturday Night Fever," has died. He was 81.
Stigwood's office said he died Monday. The cause of death wasn't immediately available.
Born in Adelaide, Australia, in 1934, Stigwood moved to Britain in his 20s and managed Eric Clapton and Cream before signing brothers Barry, Maurice and Robin Gibb, collectively known as the Bee Gees.
He later moved into movies, producing films of the Andrew Lloyd Webber-Tim Rice musical "Jesus Christ Superstar" and The Who's rock opera "Tommy," as well as disco drama "Saturday Night Fever" - set to a Bee Gees soundtrack - and the nostalgic musical "Grease."
Lloyd Webber paid tribute to Stigwood on Twitter, calling him a "great showman who taught me so much."
