Boyzone’s Keith Duffy broke down in tears tonight at the premiere of the group’s new tell-all documentary as he remembered his late bandmate Stephen Gately.

He was joined by Ronan Keating, 47, and Shane Lynch, 48, on Monday night as they reunited at the The Roundhouse for the premiere of their new Sky docuseries Boyzone: No Matter What.

The show features never-before-seen footage of manager Louis Walsh, who chose not to attend the premiere, and the band members, as well as interviews with those closest to the group.

Mr Duffy, 50, wiped his tears as he tried to speak to the audience about Stephen who died from acute pulmonary oedema, a build-up of fluid on his lungs, in 2009.

Fellow Boyzone member Mr Keating stepped up to cover for Mr Duffy as he was overcome with emotion.

But even he couldn’t stop his voice trembling as he said: ‘I’m sad for Stephen.’

After pulling himself together, Mr Duffy explained the sparkly red leopard print shirt he was wearing was a tribute to Stephen.

‘He loved red, he loved print and he loved glitter!’ he said, prompting cheers and laughter from the crowd.

He then pointed to Stephen’s brother Tony who was in attendance and thanked him for coming.

Before bursting into tears, Mr Duffy had admitted he would never let his children enter the world of showbusiness after his experience.

He said: ‘Honestly, it’s like another world. I’ve got children and you try to bring up your kids and teach them right from wrong and give them a good life. 

‘We were given an amazing opportunity. We travelled the world. We came from humble beginnings, we didn’t have a lot of money. We were put on private jets and in five-star hotels. 

‘You think “what the f**k is your problem? enjoy yourself!”. It’s so difficult to explain.

‘Yes, we had a great, unbelievable, life experience. Would I put my children through it? No, I wouldn’t, absolutely not.’

Mr Lynch also touched on the realities of being thrown into the world of pop stardom at a young age and the misconceptions around how glamourous it really is. 

He said: ‘We did it as young men thrown into this world of pop stardom. The world of pop stardom is not what you think, all glitz and glam and beautiful. It’s a deep and dark world in many ways. 

‘The three hours that are put together here is not enough. It really is not enough.’

Mr Keating addressed the absence of his former bandmate Mikey Graham, 52, who he has had a rocky relationship with.

He said: ‘I heard that Mick is not here. It was his choice to not be here and I respect that, we all respect that. 

‘I would have loved for him to be here but he’s obviously seen the film, he is very proud of the film and he sends his love to everybody. 

‘It’s his decision, it was easier for him and I respect that and understand.’

Mr Graham previously admitted he had grown tired of the ‘toxic’ music industry and left it all behind for a quiet life in rural Ireland. 

The star – referred to as ‘The Quiet One’ during his time in Boyzone – has revealed he hasn’t spoke to his former bandmates since their final show, five years ago and admitted in the docuseries, he doesn’t wish to ever go back.
