How to play Dumb Ways To Die on guitar

This is a great tune and as soon as I heard it I wanted to play it. I couldn’t find the chords on the interweb so I’ve transcribed it for your playing pleasure. Any errors are my own. As far as I can establish the lyrics are by John Mescall and Pat Baron from McCann, and the music is by Ollie McGill. The song is performed by Tangerine Kitty. I’ve tried to keep the explanations in the video to a minimum and I haven’t sung the song as no one should have to endure an old man singing in falsetto.
