Doug Walker is an English singer and songwriter based in Manchester. Walker is best known for his single "The Mystery", which rose in popularity after being played by BBC Radio 1. This happened when Walker gave a copy of the recording to DJ Chris Moyles after turning up outside the Radio 1 studio on 28 August 2007 at 5.30 a.m. Subsequently, it was played at 7.20 a.m., and the radio station was inundated with emails and SMS texts. This exposure led to a life-changing opportunity for Walker, in which he met with record labels and signed with Warner Bros. Records on 12 October 2007.
