I think you heard this from Newgrounds, because the artist is Allergic to Life Productions.
noveltychristmasmusic.com/2016/01/the-future-star-wars-4/ That video might be the only remaining evidence of it, because the original has been taken down by YouTube. And it is from 1999, so it is probably on a older version of Newgrounds.
