Playing Catch-Up

So what’s the deal with this “Ketchup” song? Is it “The Ketchup Song”? Or just “Ketchup”? And why all the commotion?
I haven’t heard it. So I have no idea what all the hubbub is, or if, indeed, it warrants the hubbub.
Am I missing anything, other than an opportunity to pun away to my heart’s content with all sorts of condiment-related hilarity?
