"Behind the Crimson Door" is the sixth track on Dark Light. The song was performed through out the 2005 and 2006 tours in support of the album. Ville once said the song was about anal sex, but then retracted his statement stating that it was merely a joke. He then mentioned in concert on November 9th, 2005 that the song was inspired by the latest Hellraiser film Hellraiser: Deader (also known as Hellraiser VII: Deader).
