83-year-old Margaret Mackie suffers from dementia and lives in a nursing home in Scotland.
Last month, one of her helpers sang a duet with her at their annual Christmas party and it was so good, he booked time in a recording studio with her.
They covered the Frank Sinatra song "My Way", and posted it to iTunes last week and less than 24 hours later, it hit number SEVEN on the iTunes U.K. Pop Songs chart.
You can buy it on iTunes for a buck. Just search for "My Way by Margaret Mackie."
All the proceeds are being split between two charities, the Alzheimer's Society and Dementia U.K.
