He worked for years in a factory to support his family. But he always kept singing.

Now McDermott, 80, is struggling with Alzheimer’s disease but he can still hold a tune.

His son Mac McDermott, 40, has been recording the performances whether on stage or in a car and is sharing them in an attempt to raise money for the Alzheimer's Society, a charity that offers support and funding for dementia research.

"Now it's become a thing that we both do together,'' Mac told the "Today" show. "It's really bonded us. He's become my best mate, and I have a sense I've become his."

McDermott is in the running for "Creative Fundraiser of the Year" through JustGiving.

Ted recently celebrated his 80 birthday. Attendees joined "The Songaminute Man" as he belted out "You'll Never Walk Alone" as well as "New York, New York."
