The best and worst pop comebacks
Starting out, Take That were looked down upon as teen totty. But since reforming in 2005 the group have never been more credible - not even the departure of Jason Orange had impeded their progress.
Earlier this year the Britpop icons released arguably their best ever LP, The Magic Whip, followed up with a triumphant tour including a stop-off at Electric Picnic.
The heavy rock legends reunited just once - for a fundraiser gig at the London's O2 arena in 2007. Yet, those who were there say it was one of the most astonishing concerts staged at the venue.
The Spice Girls
History has not been kind to The Spice Girls' (pictured) bubble-gum anthems and their 2007 comeback tour was judged underwhelming, with dates in Asia, South America and Australia cancelled amid slow ticket sales.
Since coming out of retirement, Boyzone's career has been a story of even diminishing returns. Many people were not even aware that they released an album - From Dublin To Detroit - in November of 2014.
The iconic hip-hop duo seemed unaware they were supposed to have joined forces once more when they got back together last year. It was later confirmed they would not be working on new material.
