Gibb was in a coma for more than a week this April. After waking up, Gibb’s doctors released a statement revealing he had advanced colorectal cancer and marveling at his “extraordinary courage, iron will and deep reserves of physical strength.” They warned his future was “uncertain.”

News of Gibb’s death broke shortly before the Billboard Music Awards began in Las Vegas. Hosts Julie Bowen and Ty Burrell of “Modern Family” paid tribute to the Bee Gee at the top of the show, Billboard tweeted.

On Gibb’s Facebook page, where news of his death was posted Sunday afternoon, fans shared their condolences and thanked the songwriter for his contributions to music. His brother Barry Gibb has not released a statement.
