The Six English Rockers

Another scene out of the ordinary is the dressmaking establishment where from behind hanging dresses the girls give a “headless” dance in the air, only the feet being visible beneath the skirts.
There are four schenes, one in which Nellie Florede, who now leads the young Englishwomen, sings "I'm Sorry," given over altogether for a change.
If the girls were to remain behind these dresses until the second chorus before disclosing themselves, and Miss Florede to sing one verse of the "Sorry" song, it would benefit. The light effects are pretty and handled nicely, the costuming pretty and expensive, wile Miss Florede has a sopranno voice of quality, looks well and heads the company with credit to herself.
