Well, me I love Lindisfarne. Or even Steeleye Span. No problem here
Yeah, Tears is good and like I said - something like Journeyman wouldn't be too bad as well.
It's only a matter of proportions - for example of the various Maiden influences I have read about, the only one I don't like all that much is Wishbone Ash and the reason is
exactly that - too much acoustic strumming and shuffles and whatever, it reminded me of the middle-period Grateful Dead. Yes, I know what I have written about Lindisfarne and such, but those are different bands with different goals. As are Genesis, by the way. Maybe I've started with a bad album (Argus), but sometimes too much acoustic is not such a good thing.
So far Maiden have used the acoustic arrangement wisely (bar the occasional unnecessary intro, e. g. The Reincarnation of Benjamin Breeg, where after two minutes an utterly different song starts).
By the way, it would be great to see Journeyman live. However, I'm afraid that "the songs that we do are oft interred with their albums".
