High Neck Gillian Lynne, 25, went dancing yesterday on a roof 122ft. above the streets of London. She was rehearsing at the Colisean Theatre, St. Martin's-lane, for her part in the British production of the American musical how, "Can Can," which is to open at the Coliseum next month. Why dance on the roof" Gillian said; :Because it's warm and funny up here". In the background are the spire of the Church of St. Martin's the Fields and (on right) Nelson's Column.
