Blue are an English R&B group consisting of members Antony Costa, Duncan James, Lee Ryan and Simon Webbe. The band originally formed in 2000, releasing three studio albums that all peaked at number one in the United Kingdom alongside releasing 16 singles, over a four-year period. The group also worked alongside artists such as Stevie Wonder, Elton John and Lil Kim. In late 2004, the group announced that they would be going on a two-year hiatus and released their first compilation album, Best of Blue on 15 November 2004. In 2005, the group announced that they would pause and go into hiatus to allow some members to develop their solo careers.

On 28 April 2009, Blue announced that they had reformed, and would return to the stage in the summer of that year. The band reunited once again on 29 January 2011 and represented the United Kingdom at the Eurovision Song Contest 2011 in Düsseldorf with the song I Can, coming in 11th place with 100 points.
