Doug Walker is an English, Manchester-based singer-songwriter. Walked is best known for his single "The Mystery" which saw a rapid rise to notoriety after being played by BBC Radio 1. Walker gave a copy of the recording to DJ Chris Moyles turning up outside the Radio 1 studio on 28 August 2007 at 5.30am. It was played at 7.20am, and the radio station was inundated with emails and SMS texts, resulting in Moyles playing the song seven more times that week. As a result Walker met with eleven record labels and signed with Warner Bros. Records on 12 October 2007.
