I must admit, at the time, thinking back, I was slightly puzzled why this tune was so popular. It's pleasant enough, but IMO not any better than many other tunes by other artists. And IIRC HJ never followed it up with any more hits. Maybe as Leadbelly says, it somehow got a lot of airplay or something? I can't recall when I first heard it, but it was probably already in the charts by then.
