It was released in the United Kingdom on 14 April 2014 as the third and final single from his fourth solo album, Since I Saw You Last (2013).

"Since I Saw You Last" tells the story of Barlow's struggle to become a successful solo artist after Take That split in 1996, and how the media backlash against him in favour of bandmate Robbie Williams left him in the verge of breakdown, leading to his eventual departure from his record label.

The song is described as one of survival against the odds and emerging stronger than before, where Gary passionately sings about being a 'dead man walking' and having to accept the events in the past and remember the lessons learned.

Barlow asked fans to send him home movies and examples of them overcoming adversity that would appear within his music video, as a way of replicating his feelings of determination told in the song and demonstrating the resilience of human nature.
