Repeating their service of last season, the musicals of Broadway are again rendering the national anthem at the beginning of certain home games of the New York Yankees baseball team in the Bronx. Journeying from Broadway to the Bronx for Aug. 14's 7:35 PM game against the Texas Rangers will be the cast from the Broadway hit Rent. The game will air on New York radio WABC-AM 770 and be televised on New York Channel 11. -- By Robert Simonson
