Once Upon a Mattress is going all-out for the kid vote. Taking its cue from the League Of American Theatres & Producers' "Kids Night On Broadway" promotion earlier this winter, the Broadway revival has declared Thursdays as "Kids' Nights." As of March 27, for every full-price adult ticket purchased for a Thursday night performance of the Mary Rodgers/Marshall Barer musical, the buyer gets one child's ticket free. Patrons can buy tickets either at the box office on West 44th St., or by phone at (212) 947-8844. In other Mattress news, the Gerald Gutierrez-directed revival officially released its original cast CD March 25 (see Playbill On-Line story).
Once Upon A Mattress opened Dec. 19 at the Broadhurst Theatre.
