'Nellie is singing at a Concert Hall, in Liverpool. The Lantern says: Miss Nellie Power, the lady who is now delighting the audiences at the City Varieites Theatre, is a vocalist of such a rare order that she elevates the music hall in which she is engaged into a classical concert hall; while her serio-comic efforts - notably ''La-di-da!'' - are such as to command admiration for the delicacy of treatment of subjects supposed to be unfit for feminine representation.'
