Westlife soared to fame in 1998 when they were formed in Dublin, with the original line-up also featuring Brian McFadden, who later left in 2004.

The group broke hearts of fans around the globe when they announced plans to disband in 2012 before all embarking on respective solo careers over the years. 

In October, Westlife announced their return - with both new music and an anniversary tour - as Shane delightedly revealed: 'We still have a lot that we want to achieve as a band and we want to bring our new music to fans all over the world'.  

Band manager Louis Walsh gushed to MailOnline about the boys: 'This is Westlife back at their very best. The shows at Croke Park were incredible and you can see it all in the Dynamite video. 160,000 fans across two nights are all captured in the video. 

'The band is bigger and more popular than ever. There is much more to come. They’ve got big TV appearances lined up over the next couple of months because people want to see more of the boys. The album will be released in November. We’re also looking at touring again next year. It is an exciting time.'
