28 WRCWILL REPEAT MEMORY CONTEST Grand Opera Stars Will pear Incognito Tonight. Elizabeth Winston on Bill. The second of the series of music memory contests, featuring famous grand opera stars, forms the “Bruns- wick Hour of. Music,” to be broad- cast tonight by WRC in conjunction with WJZ, New York, and WGY, Sche- nectady. The artists will be present- ed incognito, as well as the title of ir selections and the composers. Another headline attraction sched- uled by WRC is a recital by Eliza- beth Winston, prominent concert pianist and recording artist, which will be “piped down” from WJZ. Miss Winston will play from 10 to 10:13 o'clock. Wile to Speak. The “Brunswick Hour of Music” will be broadeast between 9 and 10 oclork. Tt will be preceded by such features as Frederic William Wile's| weekly resume of the political sit ation in Washington, Leonard Hall's review of the current attractions at the Washington theaters and dinner music by the Meyer Davis Willard | Hotel Orchestra. 1 Other attractions WRC include Peggy dren’s perfod, which will open the program at 6:45 o'clock: a recital by| Katherine Travis, soprano, of Pitts- burg, and a program of dance music by the Meyer Davis Cafe Le Paradis Band. The dance program by the Le Para- éis Band will go on the air at 10:15 o'clock as the concluding feature, Spencer Tupman, director,-has planned some novelties for the program. scheduled by | Albion’s chil- Local Rafig Iflefiminment Tuesday, February 10, 1925.
