The news that Robin and Barry Gibb will once again perform together comes six years after their brother and fellow group member Maurice Gibb died at age 53 of complications resulting from a twisted intestine.
Shortly after Maurice's death, his surviving siblings vowed they would not sing together under the Bee Gees name. They later said they would reconsider doing so when the time is right.
"The two of us are getting back together again as we speak," Robin Gibb told BBC Radio, adding that he and Barry had "got through the breakwater of emotions" following their brother's death.
"It's an emotional thing when you lose someone that close," he added.
Robin Gibb told the BBC in June 2008, five years after Maurice Gibb died, the Bee Gees may some day reunite.
