Princess Margaret watches a traditional English Folk Dance then joins in with the next one.
Titles read: "LONDON - PRINCESS MARGARET AT CHRISTMAS DANCE".
Various shots of Princess Margaret arriving at the Headquarters of the English Folk Dance and Song Society (probably Cecil Sharp House in Camden). She sits with Lord Snowdon (Anthony Armstrong-Jones) and watches men and women in traditional English costume (lots of bells and ribbons for both sexes) performing an English folk dance. Looks like Morris Dancing with partners.
We then see Princess Margaret joining in another group dance, partnered by an old gent. She is not exactly dressed for the occasion (long slim evening gown) and looks a little uncomfortable at times.
