Submitted by voxdog. Here’s what he had to say about it:
Arrangement info: the song is in C#m but transposed here to F#m for easier ukulele’ing. The Mumford’s use an DADF#AD tuning capo’d at 2nd fret thus the interesting chordings. This is not the full song once you hit the 5th verse since much of it is repetitive. Here the outro (the “ah” sections) are shortened. Enjoy.
