Zumba/Older song name/artist?

So in Zumba class, we dance to this one song. I have no idea the name of it. But some lyrics are swing, swing, I like to see your body moving; I like to see you get it high. It has a bit of a 1930's beat to it. It's not by savage. It basically repeats swing throughout the chorus. Sorry I'm not very specific! Anyone have any ideas?
