Blood Red Sandman Blood Red Sandman "Blood Red Sandman" is the second single from Lordi's second album "The Monsterican Dream". The song's original title was "Blood Red Santa", but Asko Kallonen from BMG Finland thought it was inappropriate for a Christmas hit and many people said they would ban it because it painted a violent image of Santa.
