I'm old school too, and "Evergreen" is one of my
favourites!
MIO also sang an English version of Evergreen, called Starbright, which was also on the 0083
soundtrack CD (although I don't think it was actually used in the
series). Have you heard it? The music and arrangement are
identical, but the English lyrics aren't a direct translation of
those in the Japanese version.
However, my all-time favourite anime song is Tenohira no Uchuu ('The Universe in
the Palm of Your Hand') which is the ending theme heard only in the
final episode of "Key the Metal Idol." It's an incredibly powerful
and moving piece sung beautifully by Iwao Junko (who voices the
main character Key in the OVA).
You can download an MP3 of Tenohira no Uchuuj here and listen
for yourself.
