Emotional video of a Vanderbilt University Medical Center nurse singing to a terminal cancer patient has gone viral.

Three weeks ago 63-year-old Margaret Smith was admitted to VUMC because of rapid decline in health. She had been suffering from liver cancer for about a year.

After a procedure, she waited for a liver transplant, but doctors told her that her health was in poor shape for a transplant.

She was later moved to a nursing home in Cookeville, Tennessee, where she died Wednesday, but before leaving the hospital, a nurse made a special moment by singing to Smith.

Before her release, Margaret's friend recorded a video of VUMC nurse Olivia Nuefelder singing her favorite song "Dancing In The Sky" by Dani and Lizzy.

The video was posted two days ago and has reached 1.6 million views so far. The video is very touching to watch.

Margaret called her an angel.

Margaret was described as a widow who loved life, people and the Lord.
