Kacey Musgraves helped bring Christmas cheer to the elderly patients at an assisted care facility, but she seems to have gotten a lot more in return.

The country singer recently released her first holiday album, A Very Kacey Christmas, and she was in Wilkes-Barre, Pa., on Friday (Dec. 9) for a tour date in support of the album.

While there, she made a non-promotional stop at Little Flower Manor, an assisted living facility. She and her band gave an old-timey performance of several Christmas tunes for the residents there, including "Christmas Don't Be Late" and "I Want a Hippopotamus for Christmas," which she shared in the clips below.

Afterward, the celebrated singer-songwriter turned to Instagram to rave about the experience.

"Y'ALL. We had the best time this morning," she writes. "The power and memory attached to music is extraordinary. Starting now in the cities we come to I will do my best to make it to as many of these places as I can. I was inspired to after seeing the documentary Alive Inside -- which I highly recommend."

Alive Inside follows the stories of several healthcare advocates, including social worker Dan Cohen, founder of the nonprofit organization Music & Memory. According to the film's website, he "fights against a broken healthcare system to demonstrate music’s ability to combat memory loss and restore a deep sense of self to those suffering from it." Alive Inside won the Audience Award at the 2014 Sundance Film Festival.

Musgraves was particularly touched by one of the patients at Little Flower Manor.

"One woman (Lillian) who was turning 94 today told us that it's our generation's job to 'do better than her generation,'" she shares. "Grab an elder and squeeze them tight. We're lucky to have them around!"

Musgraves adds that she didn't post about the experience to make herself look good.

"I am just blown away by the impact that this business I am lucky to be able to work in brings!"
