Barry Gibb will receive the GRAMMY Lifetime Achievement Award on behalf of the Bee Gees on Sunday, but the distinction is bittersweet as his brothers and fellow Bee Gee members Robin and Maurice have passed away.
"Of course there will [be a void]," Barry told ET. "But I always believe they're close."
After astounding doctors by waking up from a coma, Robin passed away in May 2012 after battles with colon and liver cancer. Robin's twin Maurice succumbed to complications of a twisted bowel in 2003 and brother Andy, who was not in the music group, died of a heart condition called myocarditis in 1988.
Of all their songs Barry admitted that he prefers hits like "How Can You Mend a Broken Heart" and "Lonely Days" over "Stayin' Alive," because of the high notes in the disco anthem.
The Bee Gees were the face of disco along with Saturday Night Fever star John Travolta, who sent a special message for Barry.
"Barry, you know I love you," John said. "Thank you so much for everything you've done for me and everything I've done for you."
Barry was touched by the message, acknowledging the cultural impact that the Bee Gees and John had on the world through the 1977 dance film.
