"A Nail Won't Fix a Broken Heart" chords

Looking for some help with the mandolin chords for "A Nail Won't Fix a Broken Heart" by The Low and Sweet Orchestra.

Just saw a video of them playing this song live. Very spirited mandolin rhythm accompaniment. Can't quite get the chords and I'd like some help if anyone knows.

As always, thanks for your help.

The chords are E A and D. The first two stabs are D then the main melody is E D E A D E D D E. For the chorus it goes A D E D E D E and repeats. They vary where they throw i the A's and D's, but those are the only chords in the song.
