Robin Gibb: 2003
Robin Gibb is pictured as he arrived at a memorial service for his 53-year-old twin brother Maurice back in 2003. 'Mo', as he was known by family and friends, died following emergency abdominal surgery.
There's no doubt that the harmonies with his twin Maurice and older brother Barry helped create one of the best-selling groups of in pop history. It's hard to imagine any of them singing long-term with other people.
