Teen with brain cancer sings Katy Perry’s ‘Roar’

A Toronto teen's recording of Katy Perry's Roar added a new note of inspiration to the tune as she belted it out in the midst of her battle with brain cancer.

When Olivia Wise sings that she has the eye of the tiger, she's a fighter and a champion, and you're going to hear her roar, it's easy to believe. In a video uploaded this week, the teen, unable to stand, sits at a studio microphone performing her softer version of the hit song.

The description says Wise recorded the song on Sept. 6, the first time she had ever stepped into a recording studio:

She couldn't walk or stand, she didn't have her full breath or the energy she used to, and she was managing her new pains and new limitations. While her physical condition was rapidly fading, her spirit remained untouched.

Olivia is a fighter and has gone through the fire, in fact, she was going through the fire while she recorded this song, but you wouldn't know it, because she was dancing right through it. She is an inspiration, a champion, and my hero. This is her Roar.

Olivia's cousin, Jeff Kassel, told Yahoo! Canada News in an email that Canadian producer Jon Levine, a friend of his, gave her the chance to record the song in studio.

"Olivia loves to sing, so she loved just having the experience of being in the studio and to have a recording of her own. The attention and positive support that the video has received has been such a pleasant surprise and a source of excitement," Kassel said.

Refinery29 reported Olivia's family hopes she might get to meet Katy Perry if she sees the video.

The musical ability of another young cancer patient, Zach Sobiech, brought him international recognition after his death from the disease in May. His original song Clouds has more than 8 million views on YouTube.
