That's my point though that not all of the "lads from the east end" vibe is gone on NOTB and that if you swapped songs between Killers and NOTB and swapped production + singer too, many of the songs could have gone on either album. Anyways, yes NOTB is a stepping stone album for sure though, but there's definitely still some East End/Killers vibes in 22 Acacia, Children of The Damned, Gangland, Invaders...
Come to think of it...Hearing the 1977-1981 Paul Di'Anno do 22 Acacia would be really interesting and I don't think it would have been bad!
