Paul Harvey and Sir Tom Hunter: Composer with dementia inspires £1m donation

A billionaire has made a £1m charity donation after being inspired by the story of a former music teacher with dementia who composed a piece based on just four notes.

Sir Tom Hunter told BBC Breakfast that when he saw a video of Paul Harvey, 80, performing the piece, he immediately wanted to donate the money.

The donation will be split between the Alzheimer's Society and Music for Dementia.
