The Sweetest Duet By A teenage Girl & Her Elderly Grandpa

An unlikely musical duo has emerged of two family members rocking the stage like real pros. 81-year-old Frank Nardone and his 18-year-old granddaughter Brooke Falls shared this beautiful rendition of "Somewhere Over the Rainbow."

The video starts with Brooke holding up a sign reading 18 which she then passes to her grandfather sitting next to her, but swaps it to read 81. Did you ever figure this interesting number swap before! We think it is pretty neat for presenting the age gap between two generations. Truly impressive!
