Does anyone know (or have time to work out) the chords to the song Harp by Stiff Little Fingers (http://uk.youtube.com/watch?v=aettcRoW8uQ)

I know there's a version on UG, but:

1) It doesn't seem right to me
2) I want a version that can be played without a capo

I'm not bothered about the intro or anything, just the chords.

Thanks guys.
