Even Oprah Winfrey knows that if you want to transport yourself back to the 1960’s, there’s no better show to do it with than Jersey Boys. The daytime diva invited the Chicago cast of the hit musical to be a part of yesterday's throwback tribute to the Mad Men decade on her talkfest. The Boys—comprised of Michael Cunio (Tommy DeVito), Michael Ingersoll (Nick Massi), Dominic Scaglione, Jr. (Frankie Valli) and Shonn Wiley (Bob Gaudio)—charmed the audience with a medley of “Sherry,” “Big Girls Don’t Cry,” and “Walk Like a Man”, then were interviewed by the queen herself. What did Oprah have to say about the swinging performance? “That was swell!” See for yourself!
