Fantastic, no wonder you were excited for them to arrive!
Go and play '
The Tongue of Fire' really loud now in celebration!!
As for Maiden, Killers was the first one I ever heard, it's a funny story because I wasn't even remotely a metalhead at the time, probably like 11 years old and my neighbour had an Amiga computer and the screen saver was Killers and I was OBSSESSED by the artwork and bought it on tape from 'Our Price Records' and everything went downhill from there
