Adventure Time Original Demo Songs for Incendium by Rebecca Sugar

The third season finale of Adventure Time is an episode by Rebecca Sugar and Adam Muto that looks at Finn's unrequited love for Princess Bubblegum (plus a few surprises!) These two songs from the episode, one sung by Finn and the other by Jake, have a parallel structure both in melody and lyrics. (BTW, there's a change in the lyrics from the demo to the episode—see if you can spot it!) Rebecca sketched the title card for the episode, and the final was painted by Martin Ansolabehere. You can see both versions in this video, as well as preliminary sketches that Rebecca drew when planning the storyboards.
