Westlife have announced a follow up to their 2002 Greatest Hits Volume 1 album, "Unbreakable". As the fourpiece performed their final UK date on their Gravity tour, Shane revealed that a Greatest Hits album is planned for November, which will feature "four new singles". Fans won't have to wait that long for a new release however; "We're going to release a single this summer" said Shane. "We can't wait!" added Mark, "it is the first time in about ten years that we've put something out in the summertime so we hope you're going to buy it". Throughout the concert at Birmingham's LG Arena, the lads showed their gratitude to RCA for giving them new opportunities and at one point Shane made an apparent dig at their former label Syco saying "we wanted this to be the second single from our Gravity album but it didn't happen... Anyway, things have changed now". Last month, Nicky said "Truth is yes we have moved on from Syco records after a fantastic 13 years. But it is time for a change and it's very exciting." Westlife are on tour with Kian's band Wonderland who release their debut album in May.
