I've been slacking. "Updates whenever" indeed.
I'm more of a fan of Bruce's voice but Paul di'Anno could beat him in a fight any day, Killers is up there with Powerslave, Somewhere In Time and Seventh Son... and Purgatory totally slays. I'm just going to bet that that riff was ripped off by everyone and be done with it and if you don't know what that riff sounds like it's about time to hand in your leathers.
