Their 2008 tour started out as just one date, but following phenomenal demand the four-piece band added a third date at Sheffield Arena on Sunday 25th May.

Promising an evening of polished and seamless pop precision, Shane, Mark, Kian and Nicky will perform tracks from their latest album Back Home, as well as their biggest hits from their vast catalogue.

The band toured last year with The Love Tour, which visited countries across the globe, stopping off in Australia, South Africa and the boys' home city of Dublin.

And on arrival at London's Wembley Arena, it was declared that the boys had sold more tickets at the venue than any other act and had played a remarkable record number of 23 dates there.

No modern band can compare to Westlife's extraordinary success, after they scored 14 UK number one singles and 36 million records sold worldwide, making them the biggest-selling pop act of the last nine years.

As well as performing a blend of their own tracks and covers, including Mandy, Flying Without Wings and Us Against The World, they will perform their recent hit single Home, which launched in October last year.

Home is a cover of the classic Michael Bublé song, an emotive and heartfelt ballad, beautifully showcasing the smooth vocal talents of the band.

With lush strings, soaring harmonies and indelible melody, Home creates a sound that is both soft and mellow, yet unmistakably Westlife.

Tickets for the concert are now on sale and are priced £32.50 (subject to a booking fee) and can be purchased at the Sheffield Arena Box Office, by booking online at www.hallamfmarena.co.uk or by calling the credit card hotline on 0114 2565656.
