BAFTA-winning actor Vicky McClure takes us on a deeply personal journey to discover the true extent of music's power in the fight against dementia.
Vicky starts her search for choir members, meeting people with different types of dementia and at different stages. The youngest member is 31-year-old Dan, who was diagnosed with a rare form of genetic Alzheimer's.
Vicky sets out to see the impact of music on people in the later stages of dementia, and the three-month scientific study to see whether singing in the choir has any measurable physiological effect on them comes to an end.
