Blue

The boys in Blue – still the original line-up of Antony Costa, Duncan James, Simon Webbe and Lee Ryan – play their smooth R&B. After gigging sporadically (and representing the UK at Eurovision) since their reunion in 2009, they'll have a new album to pug by the time this tour rolls around, so expect the usual ballads and chart-friendly tracks from that as well as their old hits like 'All Rise' and 'One Love'.
