Cover art for Great Balls of Fire lyrics by Jerry Lee Lewis

So I was reading about Jerry Lee Lewis on Wikipedia and it was talking about this song being viewed as controversial, and it wasn't associated with the whole, marrying his cousin thing. It made it out that this song was offensive in some way. Is there some other way to view this song that I'm not getting? Because I don't think I see how this is offensive.
