Pat D has 42 Clay Aiken concerts.

Clay Aiken (born on November 30, 1978) is a popular American singer who rose to fame on the American Idol television program, and who has become the most successful second-place finisher in that show's history, even handily eclipsing that year's "Idol" winner in sales. His first single, "Bridge Over Troubled Water"/ "This Is The Night" debuted at Number One, and became the best-selling single of the year — and he was just getting started.
