But the performance may have struck its strongest chord with the audience who heard it in person.
The video, shot July 22, shows St. Helena Hospice nurses' assistant Emma Young giving an impromptu performance to patients.
"I sing whenever I can. Every time I'm on shift, if it gets quiet then I try to sing a few songs on the piano," said Young. "It really helps to make patients and families smile and creates such a nice atmosphere."
