Soprano singing and an accompanist.
While her debut Monday was not made under the best circumstances, due to a persistent attack of laryngitis and an admitted nervousness that did not appear visible, she went over in good style, although not with the success of Miss White the preceding week. Miss Riegelman has not, or has not used, any set or hangings of her own, and the background for her first vaudeville appearance did not lend anything to the occasion. Her repertoire, comprising numbers in French, Italian and English, is well suited for voice display, but might be revised to advantage for vaudeville. She uses only an accompanist throughout her program. Miss Riegelman should make good in topping any bill after a bit of vaudeville experience.
