Any interpretations or information concerning the chords would be much appreciated. Simple works best...

Well, it's in E minor, tricky to work out though as it's quite a sparse song, mostly Guy singing and drums. I find it easier to work out chords when there's a bassline.

I'm no guitarist but the guitar 'melody' in the chorus goes
F# F# F#
F# G G G G A A A
A G G G G F# F# E
E.

and later they throw some G# (Ab) in there too.

I *think* the whole song goes G major... E minor... G major... E minor... it's not a true E minor though as I can hear a C# in places but no C.

and the bit at 2:20 or so goes
E minor/E minor (possibly B minor)
E minor E minor G major A major
until 2:57

That should be enough to be going on with for now. Forgot how much I love this song!

I have no idea what most of those chords are I think it's in E5, though.
