The Song in the episode "Doggyland"

Does anybody know something about the song called "Morning Light" on the episode Doggyland? It plays just before the end. I can't find any reference to it online except a video directly recorded from tv that has been uploaded on youtube; https://youtu.be/pU-rg3PDjiE I really want to know more about this song, and to find a proper full audio recording of it as i really like the melody and the lyrics.
Thank you!
