Fatman Scoop surprises Tube busker

He's from Harlem. She's from Harlesden. But last week hip hop star Fatman Scoop and a Tube busker came together in an unexpected way.

Isaac Freeman III, better known by his stage name Fatman Scoop, is famed for his gravelly voice and best known for the song Be Faithful which went to number one in 2003.

Little did busker Juliana Lisk know there was another surprise in store for her, as BBC London's Josephine McDermott reports.
