Aria At The 'Copa' -- Helen Traubel, center, red-haired Soprano with the great Wagnerian Operatic voice, makes a final check with other members of the show at her Manhattan opening tonight at Copacabana Club. Girls form left are: Carol Stevens, Rita Prizell, Princess Mayhall and April Kent. Miss Traubel last September refused to sign a new contract with the Metropolitan Opera rather than Knuckle down to a demand that she refrain from Cafe appearances. February 25, 1954.
