So I watched Deadpool last night (LOVED IT) and this catchy song was part of the soundtrack. I was, and still am, sure that I have heard a much older version of this, or something very similar, but I cannot place it or find it. So this’ll do for now. The song I’m thinking of is probably 50s-60s. Any ideas?

UPDATE: My friend Steve sent me a link to this, which was the one I had on the tip of my musical memory…

And then Deb informed me there was also a version by the Ikettes. Great detective work guys!
