In my opinion [track artist=UK Subs]Warhead[/track] is an anti-nuclear / anti-war song. I don't know what led you to think the lyrics are anti-religious. Even if they were, why would it ma'er? But otherwise, it's certainly not racist!

Amazing gig at Solfest, I was in the mix right at the front but my mate who was standing at the back said that after the encore Charlie Harper said "we can play a few more" and my mate could see the drummer saying "for f@ck sake" and then after those three songs Charlie said "we can play one more" and apparently the drummer said it again. We were laughing about that for ages after the gig.
