"Demons" was the fourth single taken from Irish singer Brian McFadden's debut solo album Irish Son. The song failed to match the success of his previous solo releases, and was unable to reach the top ten on the UK Singles Chart. The song peaked at #24 on the Irish Singles Chart and #28 on the UK Singles Chart, becoming McFadden's worst performing single. This resulted in his record deal being cut and McFadden parting with his record label. The music video for the song was directed by Howard Greenhalgh.
