I presume you mean Ashokan Farewell. I do it in D the original key, and chords are:

D Daug D Daug D7 Daug D D7 D D D7 D G7 G Gaug D D7 D

If you put Ashokan Farewell in the DT and Forum Search box at the top of the page, you will get tons of hits, and chords in other keys, after you click on each thread that comes up.
