Show business impresario Robert Stigwood, whose productions defined an entire era of entertainment, died in London at age 81.
His office did not give a cause of death Tuesday.
The Australian-born Stigwood managed the British rock group Cream and its legendary lead guitarist, Eric Clapton.
He also managed the three Gibb brothers, who made up the group the Bee Gees and provided the soundtrack to the Stigwood-produced film Saturday Night Fever.
The movie's disco tunes swept the world and became the unofficial soundtrack of the late 1970s, inspiring a wave of disco-themed parties, clothes and nightclubs.
Saturday Night Fever and another Stigwood-produced hit, Grease, made a superstar out of a little-known actor named John Travolta.
Composer Andrew Lloyd Webber, who worked with Stigwood on the film versions of Evita and Jesus Christ, Superstar, called him "a great showman."
