HARDtalk Extra - Singer Robin Gibb

It's been 30 years since the Bee Gees released Saturday Night Fever, one of the best-selling pop albums of all time and the best selling soundtrack ever. The Gibb family came from humble roots on Isle of Man, but the Bee Gees grew to be the fifth best-selling act of all time. Robin Gibb talks about how the loss of his brother, Maurice, still affects him and why he thinks the Bee Gees sound is still popular to this day.
