I'm not claiming to be an expert, and it's not like Bruce and I have sat down and chatted about this, but I don't think the "To Tame A Land" thing has ANYTHING to do with Frank Hebert at this point. Even back then - and I bought the album on release, so was big into Maiden at the time - it struck me more as a "hey, we're as metal as fuck; we're so metal the Dune guy wouldn't have anything to do with us! Up the irons, mate!" thing than any real behind the scenes beef.
I don't know; we all have our holy grails - someone said "Total Eclipse" and I said "YES PLEASE!" - but honestly, if you've been following Maiden for any period of time, none of this should be a surprise. Meaning, yes, some of the songs are interesting, but you weren't ever going to get "Prodigal Son", "The Loneliness of the Long Distance Runner" or "The Sheriff Of Huddersfield", and I think it was somewhat unrealistic to think you would.
