Nope, never have. I'm going to refill my coffee and give both versions a spin right now.
Good. Make sure you play the Jack Bruce sung End Of The World also from Corridors. It begins with a wicked guitar intro.
Holy crap, you're not kidding. That intro is insane.
I like Nuclear Attack; I kind of wish Greg Lake sang on the Moore arrangement. The Moore version rocks harder, but needs Lake's vocal; Lake's version is a little more... dated, shall we say.
Gary Moore is maddening, though. I listened to End Of The World first, LOVED it, then listened to Nuclear Attack and thought, "I can get past these vocals; this guitar playing is so good". Then I heard "Kidnapped" and was like... hmm. But his backing bands RULE. Ian Paice, Don Airey, Neil Murray; it's like a who's who of Deep Purple/Whitesnake/Rainbow/Sabbath history.
