Forum:Song during pilot episode

http://images4.wikia.nocookie.net/__cb20091227230730/adventuretimewithfinnandjake/images/archive/b/bc/20100401212842!Wiki.png In the pilot episode, when the Ice King flies out of his cave with Princess Bubblegum, a song starts playing. (Link for clarification: http://www.youtube.com/watch?v=ps3qlV75ZjY&t=4m56s) I've tried getting in touch with Casey Basichis to find the song to no avail. Could someone please provide me with the name of the song and where I could get it?
