- Finally tonight, America Strong, the grandmother at the piano. Tonight in Buzzards Bay Massachusetts, 95-year-old Elaine Lebar. She's been battling dementia for 15 years. Her family telling us she is slipping away with this disease. But when she sits at the piano, well, just watch when her daughter Randy requests a song. - You want me to play it?
