Various shots of a troupe of dancers doing a tap dance routine. They wear sparkly tops and shorts trimmed in black, plus some rather unlovely sparkly helmets with visors. The brisk tune is 'When the Guards Go By', and I would say they dance in the usual English style of tap - not especially stylish, though quite fun.
