Well, after 120 views but no response I'm going to guess that there are no arrangements of this piece available anywhere!
I wish my old guitar teacher, Gregory Scott, were still alive, because he could listen to a tune like this and come up with a wonderful arrangement by ear in a couple hours. He was a genius with a pitch-perfect ear. He did a chord-melody version of Sleepwalk that was outstanding; I've never heard the piece sound better! Alas, I will never reach that level. I've often tweaked and revise arrangements, and sometimes I incorporate the best of several while adding a bit here and there of my own, but I just don't have the talent to arrange a beautiful piece like this from scratch and do it justice:-(
