In the mood for some theater and dance following the Tony Awards, we hit up New York producer Ken Davenport, whose Broadway productions ('Blithe Spirit,' 'Speed-the-Plow' and 'You're Welcome America: A Final Night With George W. Bush') received four Tony nominations, for suggestions on shows worth our time (two hours, plus intermission) and money (for discounts, see www.broadwayspace.com or www.bestofbroadway.com). In the category of Best Reason to Head to NYC for a Night of Theater, his nominees are ... -- 'Billy Elliot, the Musical' (Imperial Theatre, 212-239-6200, www.billyelliotbroadway.com): 'It's the smartest show and is masterfully put together,' says Davenport, who praised its 'beautiful design.' It also danced away with 10 of the coveted Tonys. While some critics say Elton John's score is not very Elton John, Davenport says the music 'sounds like British miners singing,' which, unlike 'Bennie and the Jets,' hews to the plot. In addition, 'America loves an underdog, and when it's put in the shape of a 10-year-old boy ...' -- 'Next to Normal' (Booth Theatre, 212-239-6200, www.nexttonormal.com): Davenport calls this musical 'challenging and very moving.' It also features up-and-coming composer Tom Kitt; 'You can say, `I saw his first work.' ' As for the subject matter: 'It's a modern family with modern problems, but deeper and darker. Electrotherapy and depression are not things usually musicalized.' Alice Ripley garnered the Tony for best actress in a musical for her portrayal of the mentally debilitated mother. -- 'Blithe Spirit' (Shubert Theatre, 800-432-7250, www.blitheonbroadway.com): This is Davenport's show, so he's a bit biased, but he points out, 'You are seeing an 83-year-old legend,' referring to Angela Lansbury, who won for her role in 'one of the greatest comedies ever written.' -- 'Chicago' (Ambassador Theater, 212-239-6200, www.chicagothemusical.com): Calling it an 'old chestnut,' the producer says: ' `Chicago' has become an institution on Broadway. It's like the Empire State Building or the Met. Every visitor to New York should see it.' He also notes that among the 10 longest-running shows on Broadway, 'Chicago,' which opened in 1996, is the only musical revival. -- Off-Broadway: 'Off-Broadway is like the independent film of the New York theater scene,' Davenport explains. Among his favorites: 'Stomp' (Orpheum Theater, 212-477-2477, www.stomponline.com), Blue Man Group (Astor Place Theatre, 800-982-2787, www.blueman.com) and 'Fuerza Bruta' (Daryl Roth Theatre, 800-432-7250, www.fuerzabrutanyc.com). OK, let's see if we've got this straight. You can get WiFi on a $20 bus traveling the Interstate 95 corridor from Washington to New York, but you can't get it on Amtrak. Really? For years, travelers have wondered why the nation's premier rail company couldn't provide wireless Internet service to its passengers, especially on Acela trains, which are heavily patronized by business travelers. Most national train services in Europe provide WiFi, as does Canada's Via Rail. But hey, don't give up hope yet. 'Presently Amtrak is testing systems on the Acela express train, and we hope to have some results on that front soon,' said Cliff Cole, spokesman for the rail line. 'Our goal is to provide WiFi service,' he confirmed, although no launch date has been announced. For now, passengers can use T-Mobile service in the train stations, including Washington's Union Station and New York's Penn Station. Stay tuned for updates. Make way for Lucy, the 3.2 million-year-old skeleton of a female hominid who was uncovered in Ethiopia and is coming to New York this summer. From June 24 to Oct. 25, 'Lucy's Legacy: The Hidden Treasures of Ethiopia' will be on display at the Discovery Times Square Exposition at 226 W. 44th St. The exhibit includes other fossils and Ethiopian artifacts.
