It should be pretty well known - at least I've heard it more than once. Here's a short clip of it. It's pretty quiet, if you know it, you'll recognize it.
While I'm at it: don't need it as much as the swing song, but if you are an expert at hustle/disco, you could try your hand at identifying this one. It has lyrics ("With you I have nothing to fear / [something...] having you near..." etc.), but googling for lyrics didn't yield anything useful.
