Gibb prepares for comeback at charity concert

Bee Gees singer Robin Gibb is preparing to make a comeback at a charity concert in two weeks.

Although the 62-year-old musician - who has undergone seven rounds of chemotherapy in the last 18 months in a bid to beat liver cancer - is so exhausted he is sleeping up to 14 hours a day, he has vowed to appear at the London Palladium for the charitable 'Coming Home' concert, in aid of British troops on February 13.
