Simon McDermott is the son of 80-year-old Teddy McDermott, who was diagnosed with Alzheimer's in 2013. After the disease took its toll on Ted's relationship with his family, his memory and his mood, Simon found a unique way for them to connect again: carpool karaoke. Simon filmed the pair's joyful rendition of Quando, Quando, Quando, and put it up on YouTube with no expectations. But the video went viral across the globe, being watched by over 60 million people, and raising over GBP125,000 for the Alzheimer's Society.
