I'll keep adding things on this tab when I know them, I don't know the parts where 
Marcus just goes crazy on his guitar and I don't know how to play the
'Raise my hands, paint my spirit gold' thing either.

I might be on to something here but I think the standard tuning for this song is Open C 
and I will keep working on that aswell.

Please put in mind before posting that it's wrong that I won't sound exactly as the song 
since they got Keyboards and a Banjo aswell.
Playing Mumford and Sons song only on a guitar is not the way to play them. Have fun.

           D
And I came home

And I fell heavy into your arms

Which we've known

Will blow away with this new sun
