This song is a slightly altered version of Don Harper’s “Dark Earth” from the film “Dawn of the Dead” and includes a sample of “Snakes and Ladders” which was by Gorillaz and Roots Manuva and was supposed to be on the album, but it got scrapped. It was later released as “Soldier Boy” by Martina Topley Bird and featured Gorillaz and Roots Manuva.
