Blue are an English boy band consisting of members Simon Webbe, Duncan James, Antony Costa, and Lee Ryan.

[4] In May 1999, Lee Ryan and Antony Costa met at the ages of 15 and 17, respectively, when auditioning for a boy band on ITV's This Morning, with Simon Cowell putting the group together.

Following this, the band went to New York City to film the "If You Come Back" music video, and while there, they witnessed the attacks on the World Trade Center.

The following month, Blue were being interviewed by British newspaper The Sun and Ryan commented that "This New York thing is being blown out of proportion" and asked "What about whales?

This caused a huge media backlash that resulted in Blue losing a record deal in the United States and campaigns to sack Ryan from the group.

The album All Rise was released in time for Christmas and reached number one, eventually selling in excess of 1.3 million copies in the UK.

Sharon Mawer of AllMusic gave the album three and half stars out of five and noted, "The vocals were sung as if there was some real feeling, and that maybe is what separated Blue from their peers.

"[13] Andre Paine of the NME gave the album five stars out of ten stating, when describing some of the tracks that "All of these are fine, but so as not to alienate a single teenage girl, there's also the traditional boyband slop; 'If You Come Back' ...the ballads and various Backstreet Boys rip-offs.

The song "Supersexual" was issued in parts of South America and Spain in order to promote the band in the region.

[15] In June 2003, Hugh and David Nicholson of 1970s Scottish band Blue took the group to court, attempting to sue them and their record label EMI for £5 million.

[20] It coincided with the tenth anniversary of the establishment of the band in 2001 and a one-hour documentary, Eurovision: Your Country Needs Blue, was broadcast in April 2011 celebrated their preparations for the final.

[22] Group member Duncan James was a panellist on all episodes of the Eurovision: Your Country Needs You series in 2009, which Jade Ewen won.

Duncan James insisted that the result of their Eurovision bid won't affect their UK comeback, adding: "Should the worst happen, we're still going to press ahead with the album.

"[27] The band revealed during an interview that they had recorded a collaboration with American R&B superstar Bruno Mars for their upcoming fourth studio album.

Discussing the record with Digital Spy, Lee Ryan said: "We've been writing with Ne-Yo, and I've written at least a couple of songs on my own that will probably make the album.

We've also been working with Bruno Mars on a song called "Black and Blue" – he's sending his parts over from a demo we recorded a while ago.

In an interview shortly after the concert, the band claimed that "Hurt Lovers" was one of the first tracks they recorded after re-uniting, and that it was an obvious choice for their comeback single.

In promotion of the single, the band performed it live on Vocea României on 4 December 2012,[29] as well as embarking on an acoustic radio tour across six cities in Germany.

[30] In October 2012, the group confirmed via their official Facebook page that the title of their fourth studio album would be Roulette.

[31][non-primary source needed] On 21 February 2013, it was confirmed that the group would join ITV2's reality series The Big Reunion.

[32][33] The bands were originally only supposed to perform a one-off concert at London's Hammersmith Apollo on 26 February 2013, but the entire show sold out in under five minutes shortly after the premiere of the first episode on 31 January 2013.

[35] On 11 February, it was confirmed that following high ticket demands and the popularity of The Big Reunion, a full 12-date UK tour would be taking place from 3–12 May 2013.

[40] The song was written by group members Duncan James and Lee Ryan with Ciaron Bell, Ben Collier, Ian Hope, Liam Keenan, and Norwegian production team StarSign.

The track was co-written by the band, along with Jez Ashurst, David Jost, Martin Schmidt and Alexander Zuckowski.

In promotion of the single, the band performed it live on The Voice of Romania, as well as embarking on an acoustic radio tour across six cities in Germany.

In November 2014, Blue announced they had signed a two-album record deal with Sony Music, starting with their fifth studio album Colours released on 9 March 2015.
