John Hamilton Davidson (born December 13, 1941) is an American actor, singer, and game-show host known for hosting That's Incredible!, Time Machine, and Hollywood Squares in the 1980s, and a revival of The $100,000 Pyramid in 1991. 　　Davidson was born to two Baptist ministers in Pittsburgh, Pennsylvania, and graduated from high school in White Plains, New York, before entering Denison University.He thought about following in his parents' footsteps but ultimately decided that he would rather sing about love than preach it. 　　Davidson went on to work in various television roles, including sitcoms, game shows, variety shows, and talk shows. He is a protégé of television producer Robert James "Bob" Banner Jr., and as a tribute to his mentor, he ran a summer camp for would-be performers for two summers[when?] in the 1970s.[citation needed] As the 1980s began, he became well known for hosting, alongside Fran Tarkenton and Cathy Lee Crosby, That's Incredible! (1980–84), a human-interest/stunt-themed series whose creation, by Alan Landsburg, followed in the tradition of the 1950s television show You Asked for It.
