As soon as The Bacon Brothers took the stage Thursday night at the Southern Theatre, all you could hear was the sound of middle-aged women batting their eyelashes.The Bacon Brothers consists of Michael and Kevin Bacon, two brothers who quit their jobs to become rock stars.Michael, an Emmy-award winning composer, has written scores for “The Kennedy’s” and “The Century.” Kevin quit his job as an actor. He has performed in movies such as “Footloose” and “Murder in the First,” but is perhaps best known as the star of the fun party game “Six Degrees of Kevin Bacon.”When The Bacon Brothers finally took the stage, women were screaming. They opened their show with the title track off their new album “Getting There.” Their sound is a mix of everything from country to rock and roll to folk.The two mixed their performance with story telling, and seemed very natural on stage. You can tell that Kevin Bacon has always wanted to be a rock star, by his dancing around the stage, yelling into the microphone and constant jams with the band. He just looks so happy to be on stage and have women throwing themselves at him. The Bacon Brothers definitely have a strict demographic of middle-aged women. There were maybe a dozen men in the audience. Michael Bacon is the musician of the family. He even played the cello during a few of the songs, and opened the second act with a cover of “Unchained Melody” with only cello accompaniment. The best song in the show was “Don’t Lose Me, Boy,” a song Michael Bacon wrote when his son told him he was going to climb Mt. Everest. It was probably the only song in the show that the audience could really relate to, whether as a parent or as a child who wants to do something of which his parents would disapprove.Toward the end of the show, women were rushing to the front of the Southern Theatre to dance by the stage. When security could no longer keep people in their seats, everyone rushed to the front. That’s when the Bacon Brothers broke out into the song “Footloose,” the first of two encores.When the show was over, women were bothering stage hands for anything that the Bacon Brothers may have touched, whether it was a plastic cup, a set list, or a guitar pick, proving once again that you’re never to old to be a groupie.The brothers took the stage at about 8:30 p.m., after opening act Jeffrey Gaines. Gaines was extremely flat during his performance. He constantly insisted on the demoralizing of America, saying things like “Thou shalt not covet thy neighbor’s wife. That’s a commandment I never did understand,” as though the audience cared what he had to say. Everyone was waiting for The Bacon Brothers.
