Hello Mr. Fisher,
in your first post you're speaking about Steve and Adrian coming to your gigs in 1974. Actually, if we take the official Maiden biography "Run To The Hills", Steve met Dave Murray in 1976, when he was summoned to audition for Maiden guitarist. Steve met Adrian sometime later, because Adrian is a friend of Dave's. Actually, again if we take biography as the reference, Steve didn't know any of the original Iron Maiden recording line-up from 1978/1979 before Maiden was conceived in 1975.
To clarify my post, i'm not accusing you of anything, events that you speak of were 35 years ago. It isn't relevant to the story about Beckett songs either...i just like to discuss Maiden related things and i'm really astonished that i can discuss them with one of their idols
Regarding the plagiarism, your case is clear. Steve did use those lyrics and those melody lines.
I'm listening to Life's Shadow right now, and the instrumental part is copied note-for-note in The Nomad.
However, in Maiden's defense, not using your stuff wouldn't have changed their history and their status. 20% of the lyrics from the song from the album they made when they were already quite popular and touring worldwide, and a melody line from a quite forgotten Maiden song outside hardcore Maiden circles...
...never the less, again, your case is clear.
One more thing, copying authored stuff is really complicated. Here we have a case of direct copy of lyrics and melody lines. If Beckett took this to court, they'd won. However, Hallowed Be Thy Name itself isn't a copy of Life's Shadow. On the other hand, Dream Theater's song Regression copies Pink Floyd's Pigs On The Wing I, and no, Pink Floyd wouldn't win that court, because none of the lyrics and very few chords are the same. However, Dream Theater said, let's do a song just like POTW, both songs are openers to concept album, etc...
