Amazing Grace chords by Matt Corby

This is the first version of Matt Corby covering Amazing Grace that I could find, feel free to comment if
I've made a mistake.
There are a couple of hammer-ons that he does on chords like the C, I used this video
https://www.youtube.com/watch?v=IyozHVQlPFM for the chords so listen to play the changes right.

Have no idea if these are the right names for these chords, feel free to correct me.
