The Bee Gees. The three Gibb brothers were very close as children and spent most of their time together. Barry Gibb, born 1946, and his twin brothers Maurice and Robin, who were born in 1949, went on to become one of the most popular bands of the 1970s. All three siblings were born on the Isle of Man but moved to their father Hugh's home town - Chorlton-cum-Hardy in Manchester - to attend school.
