Craig Bierko and Bernadette Peters both introduced the numbers for their musical comedy revivals, The Music Man and Annie Get Your Gun, respectively. Music Man's Rebecca Luker and the show's barbershop quartet, The Hawkeye Four, sang "Lida Rose/Will I Ever Tell You." Annie's Nicole Ruth Snelson and Andrew Palermo did the duet, "Who Do You Love, I Hope." All of Broadway steps out to give a number or introduce one (giving the plays a chance to speak) for the free concert, Stars in the Alley, held May 31 in Shubert Alley. Everyone from the newest additions to the scene -- Bierko, Glenn Carter and Sharon Lawrence - to stalwarts like Luker and Peters, are on hand to sing and talk about Broadway theatre and the current season's offerings.
