This is an acoustic version of the song that I picked up by watching some of the live
performances of it and listening to the original recorded version. The other available
tabs for this song are pretty poor, especially if you're trying to get the original 
sound. So I thought I'd give it a go XD. Please rate and review, corrections are welcome.

Capo on 4th fret, tabbed notes in relation to capo

the original shapes played in relation to the capo)

Chorus
same chords from the pre-chorus are used in a slightly different order

If you're cold   I'll keep you warm
Dmaj (xx0232@1)        Amaj (x02220@1)           Em (022000@1)If you're low   just hold on
Dmaj (xx0232@1)        Amaj (x02220@1)       Em (022000@1)  Amaj (x02220@1)Cause I will    be your safe   ty
Dmaj (xx0232@1)        Amaj (x02220@1)     Em (022000@1)  Gmaj (320003@1)Oh don't leave home
Dmaj (xx0232@1)         Amaj (x02220@1)

That's basically it, for the last verse:
Oh how quiet, quiet the world can be
When it's just you and little me
Everything is clear and everything is new
So you won't be leaving will you

There is no guitar, but there is some sort of effect that comes in once, like a beeping
sound, I've found the best way to reproduce that sound is by playing around with the 6th
and 7th frets on the g string, while palm muting it, to make it as soft sounding as 
possible. The guitar fades back in towards the end of this verse. You can softly strum the
Dmj chord, keep increasing the volume and then transition into the chorus. You can end 
the song on Dmaj, let it ring and then repeat the intro. Hope this was helpful. If you
