Dr. Eugene Lange, American entrepreneur who discovered Miklos Gafni, the 穡second Caruso?? in Italy, is searching Australia for a ?second Melba?? He hopes to find her in attractive Rosina Rasibeck, Sydney mezzo-soprano, who leaves for London shortly with letters of recommendation to Covent Garden Opera. For that reason, he announced in Adelaide that he is returning to Sydney and will attend the Raisbeck - Nillson farewell concert at Sydney Town Hall on Tuesday night. Dr. Lange said: 穡After my successful search in Italy for a second Caruso, it's natural that I should seek in Australia for a second Melba. May 3, 1947.
