Thirty years after Americans were introduced to Alex Young, the welder who just wanted to dance, Flashdance lives on. And while leggings and leotards have disappeared from the zeitgeist, the driving rhythm of “Maniac” can still keep an audience moving. Naturally, a stage adaptation was the next logical step. Beginning tonight, interested parties can revisit 1983 at the Kennedy Center’s Eisenhower Theater, where every iconic moment, from the energetic jogging dance to the water pouring, will be recreated by a new generation of performers. It’s not the family-friendliest musical in town (those entertaining little ones might opt for Elf The Musical in KenCen’s Opera House) but chances are good you’ll leave humming the chorus to “What a Feeling.” The show runs Dec. 25 to Jan. 19 at the Kennedy Center’s Eisenhower Theater, 2700 F St. NW. $45–$150. (202) 467-4600.
