Watch the Big Reunion bands playing the 'Lyrics Game' below:
Digital Spy caught up with the former chart toppers earlier this month and decided to see if they still had what it takes to be popstars. After years of odd jobs, being mistaken in the street for members of A1 and not a single paparazzo outside their home, were they still up to the task?
Most importantly - could they still remember their lyrics?
The Big Reunion will see the retro pop acts back on stage together and attempting to resolve the issues and tensions that forced them to call it a day first time around.
In their pomp, these acts sold millions of singles, toured arenas and scored multiple No.1s, but this show will discover what happened when their musical success flagged and relationships turned sour within the groups.
The Big Reunion launches on Thursday (January 31) on ITV2.
