Since everyone's being so helpful with these enquiries, I wonder if anyone might be able to identify a track that a mate's girlfriend used to play to death about 15 years ago:

Circa 1996/7
The only lyric I can remember, from the chorus, is a vaguely rousing call of "Put on your armour" (which certainly raises the very real possibility of it being bloody awful)
Breathy-voiced, multiple harmonies over a folk song with a slightly psychedelic edge to it.
The sort of thing that a massive pothead would own.
It was on vinyl and seemed quite long - six or seven minutes - from what I recall.

Not much to go on, but any help gratefully received.
