Robin Gibb was a musician who did much to define the pop music of the 70s and 80s.

With his brothers Maurice and Barry he formed the Bee Gees.

They wrote the soundtrack for the disco era, perhaps captured best in their music for the movie Saturday Night Fever.

In December 2010, Robin Gibb joined Stephen Sackur in the Hardtalk studio to talk about his music, his family and the pressures of a pop business which drove him into a private hell of drink, drugs and depression.

In more recent years, Robin Gibb found a new sense of purpose, both in his music and in his work for a host of charities.

To the end he remained committed to song-writing and was an advocate for talent in an industry increasingly dominated by marketing rather than the music itself.

So today, a look back at Hardtalk with the late Robin Gibb.
