An 83-year-old Scottish woman with dementia is quickly climbing the UK music charts after her nursing home caregiver fell in love with her singing voice.

Because of her dementia, Margaret Mackie has trouble remembering things from day to day—but she does remember all the words to Frank Sinatra's 1969 ballad "My Way".

After Mackie and her 31-year-old caregiver Jamie Lee Morley sang a duet of the song at their nursing home's Christmas karaoke party last month, staffers were in awe of her talent.

"Her family and friends were there in the audience to witness this moment—and what a moment it was," says Morley. "For her to get up on stage at her age and have so much courage and fight and sing so beautifully absolutely blew my mind. [It's] a moment I will never ever forget."

Morley, who had bonded with Mackie over their shared love of music before, then got his elderly patient to record the song at the Ingleston-based studio Sound Sound.

Since uploading their rendition to iTunes earlier this week, it has steadily climbed up to #8 on the UK's Top 40 Most Popular Music chart, surpassing the likes of Ed Sheeran, Selena Gomez, Lizzo, and Miley Cyrus.

Additionally, since the song costs 79 pence to download, Morley and Mackie are donating all of the song's proceeds to Alzheimer's Society and Dementia UK.

Morley told the Edinburgh Evening News this week that the song's success has been "absolutely incredible".

"The feeling of getting so much awareness out there and connecting everyone through the power of music is exactly why we recorded the song as a single," he said. "Margaret's family and me couldn't be any happier with how the public have responded to it."
