Laugh Out Loud

How much of ourselves do we reveal when we laugh?

Nicola Green has recorded people laughing in every conceivable situation, creating music from the sound of pure laughter.

This programme blends that music with laughing anecdotes from various well-known voices.

This is a Laughing Portrait - from a baby's first laugh to dying of laughter.
