Whistling David Morris: Life as a professional puckerer

David Morris does more than whistle while he works - whistling is his work.

After being crowned World Whistling Champion in 2003, David gave up his job in sales and transformed his dinner party trick turn into a full-time job.

His work sees him travel the world performing concerts, as well as recording for CDs, television commercials and film soundtracks.

BBC News visited David at his home in Saddleworth, Greater Manchester, to discover some of the tricks of his trade.

Camera and editing: Ian Ellerby. Producer: Nicola Thompson.
