Purgatory 15th June 1981 1. Purgatory (Harris) 2. Genghis Khan (Harris)   Album

Iron Maiden's fourth single, Purgatory, did not do as well as other and failed to break into the Top 50 in the U.K. charts. The sleeve picture of The Number Of The Beast album was originally intended for the Purgatory single, but the band felt that the picture was just too good for merely a single, so Derek Riggs did this Eddie-devil picture to replace it for the Purgatory single.
