The recent death of Robin Gibb made this hour long tribute documentary by the BBC inevitable. Obviously not a rush job, it contains much archive footage and interviews with all the brothers.
The BBC summary can be found here.
There were actually four brothers Gibb: Barry Gibb; fraternal twins Maurice and Robin; and the youngest, Andy, who died in 1988 aged only 30. Barry is now the only one of the brothers still alive.
The brothers also had a sister. Neither she nor Andy is covered by this programme.
Without wishing to sound ghoulish, Robin's losing battle with cancer was no secret, so the Beeb had probably been working on this for some time in order to release it soon after his death.
This documentary covers the career of the Bee Gees from their childhood. Born on the Isle of Man, raised in Manchester, they emigrated to Australia as boys and were discovered by a DJ with the unlikely name of Bill Gates. The name Bee Gees was taken from both Brothers Gibb and his initials. The move back to the UK, being discovered/taken on by Robert Stigwood who worked with Brian Epstein - the Beatles' manager, cracking the States, and a long and winding road with more than a few glitches on the way, not to mention friction, and of course the inevitable substance abuse, all this is included, and more.
After their career as performers appeared to have stalled or terminated altogether, they relocated to the United States on the advice of Eric Clapton, and reinvented themselves, writing songs for other artists.
The documentary is currently on iplayer for those who can receive it; for those who can't, watch out for it on YouTube.
The Bee Gees can of course be found all over the web; start here and follow the links.
Currently, the man from SongFacts has 19 Bee Gees recordings in his database, but more will be added in due course.
