Charlie Gibson understands the power of music for people living with dementia.

These deeply personal and uplifting clips filmed at the Manchester home of Charlie's grandpa, 83-year-old Barry Carr, show Barry's reaction when watching the musical drama "The Greatest Showman."

Barry becomes visibly uplifted, smiling and clicking his fingers.

Charlie told Newsflare: "Barry is at the second stage of vascular dementia, so struggles with his memory and sleeps most of the day but has always loved his music and his musicals.

"As a way of showing dementia can be battled against and still have some fun, I recorded The Greatest Showman for him, and when visiting, I'll watch it with him. Not remembering it, he loves it like it's the first time he's watched it! Enjoy!"
