John Harris has 12 Alice Cooper concerts.

Alice Cooper (born Vincent Damon Furnier, February 4, 1948) is an American rock singer whose career spans over five decades. With a raspy voice and a stage show that features numerous props and stage illusions, including pyrotechnics, guillotines, electric chairs, fake blood, reptiles, baby dolls, and dueling swords, Cooper is considered by many music journalists and peers to be "The Godfather of Shock Rock".
