Robin Gibb passed away at the age of 62 in 2012 after a long battle with cancer and his sibling, and bandmate in The Bee Gees, Barry, admitted he still can't bring himself to perform the emotional song live.

He told BANG Showbiz: "There's a song called 'End of the Rainbow' that I dedicate to Robin, but for all my brothers [fellow Bee Gee singer Maurice and younger sibling Andy who both died before Robin]. It was very difficult; it was very emotional. It's very difficult to sing without filling up, it's one of those, I'm not sure I could sing it live without becoming very emotional.

"I sang a verse of the song to Robin when he was in a coma, about two weeks before he passed and I don't know if he heard it or not. But I sang it anyway, I'm yet to sing it live and the lyrics reflect what I hope are my correct feelings."

The song features on 69-year-old Barry's new album 'In The Now', which he admitted is an emotional record.

He explained: "It's an album that's like a journey, it's my opinion of life today, the culture, the songs reflect all those things. There's one called 'Starcrossed Lovers' that I dedicate to my wife. I've tried just to touch on all of the best influences in my entire life. It's really getting into the songwriting as deep as I can get. I'm very proud of this album.

"I don't know what my signature sound is. It's not a disco album at all. It's an album of thoughts that range 60 years and different influences over the years. It's very autobiographical, not consciously, but subconsciously. There are a lot of lyrics that are quite abstract but if you think about it deeply enough, like a painting, there are a lot of thoughts that are real behind abstract words. I hope that it makes sense."
