What can we say about the legendary “Doctor Dirty”? He is truly one of a kind. John Valby’s rapport with his audiences and his ability to mix his musical talents with his bawdy variety of “dirty ditties” have made him a staple in clubs and at colleges throughout the nation. Valby makes Andrew “Dice” Clay look like Mother Theresa, with songs like Puff the Magic Tampon, Barnacle Bill, Roll Your Leg Over and Who Gives a F**k. When he’s not playing and singing, he yells obscenities, the audience yells back, and everyone has a good time. Clad in his trademark white tuxedo, derby and bow tie, he gleefully sings his dirty songs to his faithful fans and newcomers alike. Nothing and no one is sacred around Doctor Dirty and his act is not for the weak of heart, but if you want a night filled with belly laughs and bawdy humor then John Valby is a must see!
