Pearly King and Queen of Woolwich explain the cockney tradition

Pearly Kings and Queens from across London gathered on Sunday in Guildhall Yard, in the City of London, for their Harvest Festival.

The Pearly tradition was started by a Victorian street-sweeper, and now every London borough is represented.

The Pearly King and Queen of Woolwich, Clive Bennett and his wife Kim, joined BBC London's Asad Ahmad.
