I see lots of people covering it on youtube, no links for arrangements, and no luck on google outside of a piano transcription.

Im pretty much looking for a classical guitar arrangement in sheet music, saw a couple tabs that werent quite what I was looking for, and Id much rather it be in sheet music anyway.

is there some book I should look into or is it public domain, or is there just some *other* way for me to obtain this sheet music.

finding sheet music seems to be a PITA to me, even though tabs should be harder to get at, they seem more available (even if they are transcribed badly sometimes)

have you checked out the guitar pro versions that are lying around here?

yeah but Id prefer sheet music as my teacher wont let me perform from tabs, but If I could get sheet for it I could play it as a performance piece which would be sick. (im just starting classical so I cant do crazy pieces yet)
