This just might be the best thing you'll see all week. Watch what happens when an elderly man named Henry, living in a nursing home, usually unresponsive, is given music from back in his day to listen to. Ah! I don't know whether to laugh or cry. OK, I did a bit of both.
The video features renowned neurologist and author Oliver Sacks explaining the reaction: "Henry is restored to himself. He has remember who he is for a while, through the power of music."
Henry's favourite? Cab Calloway.
