Steven Tyler sings with visually impaired girl on the street, and her voice touches millions

A 13-year-old singer got the opportunity to sing with a few lines of "Stand By Your Man" with rockstar Steven Tyler.

A video clip of their impromptu performance at the Ryman Auditorium in Nashville was shared on YouTube by her father, Greg Hardwig.

Tyler can be heard saying "we've got a big star here," and then giving her a big hug afterward. He asked her mother:

"Did you get that on video?"

Sarah was born Leber Congenital Amaurosis, a condition that affects the retina and she had been blind her entire life.

The now 15-year-old girl has been singing since a young age, and her parents encouraged her to pursue her passion. Sarah said:

“I got into music when I was about three or four years old and I just instantly knew, BOOM, that I wanted to be a musician, I want to be a successful singer-songwriter.”

She isn't holding back and has performed the National Anthem in public at more than 100 venues.

It was at one of those performances – at the Marty Stuart's Lates Night Jam in Nashville – that Tyler heard her sing.

Since singing with Tyler, she also performed Carrie Underwood's "Before He Cheats" with Graig Campbell at a CMA show.

Her parents are behind her every step of the way and are thrilled that she is living her life to the fullest, despite her diagnosis.

Fans of Tyler will recall that he performed alongside Underwood back in 2011, at the 46th Academy of Country Music Awards.

The duo sang one of her chart-toppers, "Undo It," before performing Tyler's "Walk This Way" the cheering crowd.

The following year they also performed "Just a Dream" and "Dream On" at CMT Crossroads.

Tyler isn't the only singer stealing hearts and serenading fans, as Miley Cyrus showed back in 2017 when she sang with an 8-year-old cancer patient.

Cyrus secretly arranged to serenade Julia Davidson and her parents at the Rady Children's Hospital in San Diego.

Julia was excited to see her idol and sang "The Rainbow Connection." Afterward, Miley told her young fan:

“You made me cry because you were so beautiful. That was so beautiful. Do you know how important it is to make people cry when you sing?”

Cyrus, who was a judge on "The Voice," said she should have turned her chair around if Julia was on the one on the stage.

Julia has since gone into remission but still receives regular cancer treatments
