Line of Duty star Vicky McClure introduces us to her Dementia Choir, subject of a third series on BBC1 this autumn.

She explains how science has proved the positive impact music has on those living with dementia, something she sees when she’s with the choir members and experienced with her nonna Iris, who died of dementia.

Vicky also reveals how she uses music to help her prepare for roles in dramas like Trigger Point; chats about an incredible decade in Line of Duty, and the first film she's made with her production company -  Build Your Own Films - in her home town of Nottingham.
