Pick three of them. Of course, Maiden songs covered from 1993 to 1999 don't count. Most of these covers can be found on YouTube. Feel free to mention those I have forgotten. My choice right now (in no particular order): "Delilah" - "Wishing Well" - "Burn" EDIT Addition: "Travelling in Style" (Free) "Elected" (Alice Cooper; there are actually two versions, one with Rowan Atkinson and one without him) and "Freude Schoner Gotterfunken" which seems to be an a capella version of Beethoven's "Ode to Joy" with possibly coarse lyrics (I don't understand German).
