 Of course, it was Bobby Darin who made this into a chart-topping hit. That was in 1959. I have to say, I've never liked that version. It always seemed very derivative to me. Mac is the swinging cat, the Mr. 50s cool. I felt there was nothing really original about the Bobby Darin version. It was sort of second-rate Frank Sinatra or something. Is there something I'm missing there?
