When Rachel Platten's "Fight Song" became a hit, Texas Children's Hospital knew the yearlong search for a song that perfectly illustrated the strength of its courageous young patients was over.

In a video that has warmed hearts, about 65 kids from the hospital gathered on July 13 and 14 to forget about being sick and have fun performing Platten's hit. Joined by nurses and other hospital staff, the kids held up signs indicating what illness they are fighting or which family member they are supporting in a touching montage.

Avery Speaks, 12, from Pasadena, Texas, is featured prominently in the video, lip-syncing the words in a pink shirt and glasses. Avery is battling acute lymphoblastic leukemia after being diagnosed a year ago.

"I was like, 'Oh my gosh, of course I'll do it,''' Speaks told TODAY.com. "I like how it tells us to keep fighting and keep pushing harder no matter what you're going through. Every time I come to the hospital, me and my sister listen to that song. There's good days and there's bad days, but I think the nurses all try to make it fun, and it's like home here."

Platten has also taken notice, tweeting her excitement over the video.

"That makes me so happy,'' Speaks said about Platten's tweet. "That made my year."
