"Hanky Panky" put Tommy James on the pop charts and The Ed Sullivan Show. It was also the #1 song in the US this week in 1966.
"Regarding his sudden fame, James said: "One night I was playing for 20 drunks in a bar in Michigan, and the next night I'm playing for 10,000 screaming fans in Pittsburgh. It was literally overnight. It was very unexpected, one of those winning-the-lottery type stories." (Songfacts)
