Celebrate the arrival of 2016. Or, if you’re not looking forward to returning to the factory next week, stave off those midwinter/post-holiday blues by seeing a new show or taking in others you may have missed that are in their final weekends.
A based-on-a-true-story musical that changes the names of the principals, “Dreamgirls” dramatizes in song the rise to the top of The Supremes — known here as the Dreamettes. The original Supremes — Diana Ross, Flo Ballard and Mary Wilson — are depicted in a sometimes unflattering light, along with their manipulative manager, Motown founder Berry Gordy Jr. It’s a messy, romantically entangled travail captured in such showstopping numbers as “And I Am Telling You I’m Not Going,” which has been sung by two Jennifers — Holliday in the 1981 Broadway Tony winner and Hudson, who won an Oscar for her role in the 2006 film.
WHEN | WHERE 8 p.m. Saturday, 2:30 p.m. Sunday through Jan. 17, BroadHollow Theatre Company’s BayWay Arts Center, 265 E. Main St., East Islip. Also, Feb. 6-27, BroadHollow Theatre at Elmont, 700 Hempstead Tpke.
