As soon as I saw the first cover meme post pop up, I thought of this song... but couldn't use it.
It's not a good cover, because it's horribly naff.
But it's not a bad cover, because it's deliberately naff.
It's a kind of genius, actually.
So here's my pick for "most deliberately cheesy and naff cover version", although Arlenna's picks give it a run for its money.
