Here's a sneak peek at the second instalment of series two of The Big Reunion.
The Big Reunion 2014 features exclusive and explosive accounts from former pop heroes, with revelations about drugs, fisticuffs, rows, eating disorders, shattered dreams and how the music industry can leave even apparently successful stars penniless.
Each band has just two weeks of intense rehearsals before they step back onto the stage to perform once again in front of thousands of fans.
Episode two features the biggest girl group of the early nineties, Eternal, who reveal why they’ve stayed quiet about the band’s split for 15 years.
“It just festered into something very ugly," says Kelle Bryan, Eternal. She continues: “I was aware that something had to give along the way. It just wasn’t going to be me.”
Plus, Brit Award winners A1 discuss how they struggled to come to terms with a fatal accident involving their fans.
“Thinking back now, I would have hated myself. But at the time, I thought I was brilliant.” Ben Adams, A1, say of the high point of their career.
The Big Reunion 2014 airs on Thursday night on ITV2.
