Hey these are not hard to figure, just being lazy I did a quick search, no luck, but found your query, so I had to listen and use trial and error and it is clearly in the key of Bflat which no guitarist in his right mind should use, so put your capo on the 3rd fret and use the key of G with the first 2 lines like so:
GCGCEmAmGD
GCGCEmAmGDG (just a quick D in there before the final G)

Those 2 lines are repeated, which completes a verse. There is only one different bit, the two lines starting "And if I was a flier...":
EmCGC
EmCGD
And of course the piano break is just the same as a verse. If you don't like the full sound of the chords use partials,or just notes, as you like. Beautiful song, enjoy.
