The Bee Gees singer admitted he found it "incredibly hard" after his brothers and bandmates, Robin and Maurice Gibb, died in 2012 and 2003 respectively and he's still unsure how to cope without his siblings around.

Speaking on 'CBS Sunday Morning', the 74-year-old musician said: "Incredibly, incredibly hard. Because we'd never, was never not been together, you know? It was really tough.

"The first year after the last brother passed, Robin, that was the most difficult period for me. And people have said, 'He had a breakdown.' You know, I didn't have a breakdown, actually.

''I just didn't know where to go. I didn't know what to do. And I didn't know how to be perceived. I didn't know how to perceive other people's opinions. So basically, I've been in lockdown for years now!'

And Barry can't bring himself to watch new documentary 'The Bee Gees: How Can You Mend a Broken Heart' because he "can't handle" having to relive his siblings' passings and having to address the subject.

He said: "I can't handle watching the rest of my family. I just can't handle it.

"Who would? I think it's perfectly normal to not want to see how each brother was lost, you know? And I don't want to address it. I'm past it.' "

Though the 'Saturday Night Fever' hitmaker admitted it is "lonely" performing without his siblings, he's keen to go back on the road again if the fans want to see him.

He said: "I wanna be wanted. And if people want me to do it, then, my goodness, I'd be honoured to do it.

"It's lonely up there when you haven't got your brothers. But you still make it fun. That's what counts.

"It's bittersweet. But, you know, that's one of the things we live with, is loss. And my goodness, I've learned so much from it."
