Possibly answering once and for all the question of whether “America’s Got Talent,” judge David Hasselhoff will sing during next week’s semifinal. NBC, describing Hasselhoff as the show’s “own celebrity judge and international entertainer,” says he’ll perform “Feeling Good” on Wednesday’s results show (8 p.m. Sept. 2). Hasselhoff crossed over from “Baywatch” into music in the late 1980s and was famous for being wildly famous in Germany.
