[Harp-L] What's the key of harp for this Lee Oskar song?

[Bai He <bailaohe@xxxxxxxxx>]

Lee Oskar play a wonderful music called "Forbidden Waters".
I try to play it on ten-holes. I found it should be played with Eb and
Fnm Harp.
However, both sound a little different. Would any body help me?
The music is here!
