I'm glad they didn't include the original Blaze versions, the reason i'm buying it is because the Blaze-era songs are live versions with Bruce. Sign of the Cross sang by Bruce on the Rock in Rio DVD is class and miles better than the studio version, same for Lord of the Flies on the Dance of Death DVD. The live versions by Bruce far outstrip the studio versions and so should be included on the 'Best Of...' as they are the best versions of those era songs.
I doubt new-comers will be shocked if they go back to buy X Factor or Virtual 11, it's still Maiden, just not at thier very best. It's the same for new-comers going back to buy the first two albums and finding that benefits cheat Dianno on vocals.
