Ok, so, this might prove almost impossible, because my memories of the song are VERY vague, and I only remember a handful of things about it. Any help will be greatly appreciated!
So the song has a very celtic/folk/sort-of-medieval feel to it. There may be drums, but no guitars as far as I can remember, and all I can remember of the lyrics are the humming and "we will all be [something]". It was quite upbeat and had a female vocalist. I also remember that I heard it on a mixtape which featured songs from 1994/5/6 and such, so it was probably from around then but could've been much earlier. I realise this is about as vague a description as possible... but yeah, I'm really not sure what else to tell you.
Thanks in advance!
