BROADWAY IN CARNEGIE  Lenora Nemetz, Pittsburgh’s queen of song and dance, will showcase her amazing repertoire at Lenora! Lenora Nemetz Brings Broadway to Carnegie Carnegie, 8 p.m., Saturday, December 28, at the Andrew Carnegie Free Library & Music Hall.

As a teenager, Nemetz left Pittsburgh for the Great White Way and, at age 17, was cast as the replacement for Fritzie in the original Cabaret. A protégé of  famed choreographer Bob Fosse, Nemetz first drew critical attention when she replaced the iconic Chita Rivera as Velma in the original Broadway production of Chicago. This summer, Nemetz starred in Side by Side by Sondheim.

The performance will be followed by a reception on all three floors of the historic landmark facility. Tickets are $125 ($90 tax deductible) for reserved seats in the orchestra and $75 ($40 tax deductible) for open seating in the balcony. Proceeds benefit the Library & Music Hall and the restoration of its historic facility. Purchase tickets at www.carnegiecarnegie.org or by calling 412-276-3456, x13.
