Verdict: two and a half stars.

Ever wonder what happened to that band who had a number one hit with that song?

For music fans it is a question that crops up time and time again, but thanks to ITV's The Big Reunion, those artists in pop obscurity have been able to revitalise their careers and tell us exactly what happened to them.

The show has given countless Smash Hits cover worthy artists another go at the fame game but when their latest concert rolled into Glasgow's SSE Hydro on Saturday night, it was all about the boy bands.

Featuring Damage, A1, Five, Blue, 911, 3T and a newly formed band 5th Story made up of solo artists Kavana, Adam Rickett, Gareth Gates and men without their boy bands Kenzie (formerly of Blazin' Sqaud) and Dane Bowers (lead singer of Another Level), The Big Reunion offered up a variety of boy bands who had varying success at the height of their careers.

Openers A1 - minus Paul Marazzi - started the show in style as they performed their number one cover of A-Ha's Take on Me before bringing out the guitars for Caught in the Middle.

Next up was five - minus two members, remember J never took part in the first Big Reunion and Abz has since left the band after taking part in the show's first tour.

Five are always going to be crowd pleasers with tracks We Will Rock You, If Ya Gettin' Down and Everybody Get Up.

But already we have a pattern emerging from The Big Reunion - the original line-ups were missing in action.

I doubt it mattered to most of the fans, but it somehow took authenticity out of some of the acts, and defeated the point of a reunion.

Michael Jackson's nephews 3T and 911 did however present the same format from back in the day.

Highlights included 3T's ballad Anything and 911's heavily choreographed Bodyshakin'.

Boyband Blue brought some soul to the show after Damage performed Ghetto Romance of course.

The Blue boys also had Bradley from S Club 7 out to help perform their hits, as Simon Webbe is competing in Strictly Come Dancing.

Breathe Easy and One Love were great performances, and the boys could have easily done the show without bringing in a replacement.

The interesting set from the show was the performance by 5th Story, manufactured to allow each member a chance to sing their biggest hits.

It may be that their back catalogues cannot allow the 5th Story artists to hold it on their own, but putting them together X-Factor style somehow does not work.

The show is filled with nostalgia, great pop tunes and hunky boy banders turned men - there is a lot to love.

But for me The Big Reunion show, the first time round, was a one-off and worked because it was bands people really wanted to see.

The Hydro was not a sell-out for the show, so perhaps it is a sign that it is time for The Big Reunion to move to smaller venues to entertain the die-hards.
