I've got to find a way to share all these awesome season 3 finale resources! The latest is a double feature: piano transcriptions of I've Got to Find a Way and Celestia's Ballad by DJDelta0. They sound great!
You can listen to DJDelta0's rendition of I've Got to Find a Way in the video, and Celestia's Ballad here. Then make sure to check out the sheet music, MP3, and midi resources (all in the video descriptions).
