Erin Solari said she posted the video on YouTube after the visit, which took place at a facility where Laura was in hospice care. 
Howard and Laura have been married for 73 years, Solari wrote.

“The song used in the video is ‘You’ll Never Know’ performed by Rosemary Clooney with Harry James. Our family prefers this version because everyone always said Grandma had a voice just like Rosemary Clooney,” Solari wrote on her post.

In the YouTube post on Sept. 20, 2015, Solari also shared an update:

“After posting this video to Facebook, it began to go viral and all the outpouring of love lifted everyone's spirits... including Grandma's! Hospice eventually deemed her well enough to go back home to live out her remaining few days. As of this posting my beautiful Grandma Laura Virginia is still with us resting peacefully at home. Our family along with the wonderful people from hospice are taking care of her and making sure she remains as pain-free and comfortable as possible while she prepares for her nearing departure. We all thank you so much for the love and kind words.”
