Barry and Robin Gibb, two-thirds of the Bee Gees, reunited on stage for a Miami charity concert, their first performance since the death of their brother Maurice three years ago.

The Gibb brothers performed a private concert Saturday night at the Diplomat Hotel to raise money for the Diabetes Research Institute at an annual benefit for the organization, Paul Bloch, Barry Gibb's publicist, said Sunday. The brothers performed dozens of Bee Gees hits spanning 35 years, including "Stayin' Alive," "Massachusetts," "How Deep is Your Love" and what Bloch called a stunning tribute to Maurice with the song "Don't Forget to Remember." Maurice Gibb died at age 53 in January 2003 after emergency surgery for an intestinal blockage. He had been admitted to Mount Sinai Medical Center in Miami four days earlier and had suffered cardiac arrest before the operation.
