Live at the Ruskin Arms, London, UK on December 23, 1981.
"The concert featured on this album was recorded at the Ruskin Arms, Iron Maidens favourite pub, under the name of "Genghis Khan". This special X-mas gig was one of the first with new vocalist Bruce Dickinson and happened to be on Dave Murrays birthday. "Run to the hills" and "Prisoner" were performed for the very first time and therefore contain different lyrics."
On both sleeve and labels it says that Iron Maiden, Transylvania and Drifter are on side 4. But that's incorrect. They're on side 3, and whole side 4 is the soundcheck.
