Robert Colin Stigwood (16 April 1934 – 4 January 2016) was an Australian-born British-resident music entrepreneur, film producer and impresario, best known for managing Cream and the Bee Gees, theatrical productions like Hair and Jesus Christ Superstar, and film productions including the successful Grease and Saturday Night Fever. On his death, one obituary judged he had been for a time the most powerful tycoon in the entertainment industry: "Stigwood owned the record label that issued his artists’ albums and film soundtracks, and he also controlled publishing rights – not since Hollywood's golden days had so much power and wealth been concentrated in the hands of one mogul."
