Robin Gibb, one of the two surviving members of the Bee Gees, passed away on May 20 after a struggle with colon and liver cancer.

As a third of the immensely successful Bee Gees, Robin and his brothers had successes in the late 1960s with classics such as “I Started A Joke” and “To Love Somebody,” but dominated the charts throughout the 1970s with the singles “Night Fever,” “Stayin’ Alive” and more, buoyed by the triumph of the Saturday Night Fever soundtrack. The decade yielded the group nine number 1 hits. Following the disco backlash, the Bee Gees found success writing material for other artists and Robin embarked on a solo career that produced three albums.

Robin and his twin brother Maurice were afflicted with the same genetic disorder–a twisted colon–which claimed Maurice’s life back in 2003. Though Robin underwent surgery in 2010, intestinal issues continued to plague him. In April, he slipped into a coma after surgery and a bout with pneumonia.

Robin is survived by his brother Barry, wife Dwina, sons Robin-John and Spencer, and daughters Melissa and Snow Robin
