Here are the four progressions played. My advice if any is to nail the bass note and just let the rest flow. I haven't tabbed out every note of every chord below, just the ones I hear, but take it from me the chord shapes are as simple as A minor, C and F, just with the emphasis on the bass (root) notes.
