MILFORD - Three times International Whistling Entertainer of the Year Steve Herbst will be whistling on stage after the Black Bear Film Festival’s Oct. 15 screening of “Pucker Up,” a humorous documentary about his competing for the title of World’s Best Whistler. Herbst, who lives in New York City, has been whistling seriously since he was seven and asserts that “whistling is a legitimate musical artform. A retired advertising executive Herbst says he is, as far as he knows, the world’s only full-time professional whistler. Herbst does live performances and has a CD, titled “Broadway and Beyond.” You can hear him on his website, www.stevethewhistler.com. “Pucker Up”, by award-winning directors Kate Davis and David Heilbroner, is set in rural Louisville, North Carolina, site of the annual whistling convention where competitions are held.
