I've linked it to the exact spot of the video where the song plays. In case it doesn't work right, though, the starting point is around the 3 minute, 38 second mark and it ends at around the 4 minute, 30 second mark. It's from the Tim and Eric Awesome Show episode "Greene Machine" and it plays during a movie trailer for a movie called "Little Dancing Man". It could be an original song made for the TV show itself, but it sounds too professional and too familiar to me. It almost sounds like an inspirational song used in some 80's or 90's movie, but I just can't place it.
By the way, I know the video is really silly, but that song has been stuck in my head since I first heard it and I still can't identify it (assuming it's a real song). I'm not the only one who think so either since I've seen a handful of people asking around about the song, but they can't figure it out either. Thanks for any and all help.
