A 16 year old cancer survivor makes an appearance on Ellen after her video of her singing got noticed by Ellen. Caly shares her inspirational story with us and how the “Fight Song” became her personal theme song as she battled the cancer. Ellen decided that Caly needs to sing the song live on her show so she brought a special guest to the show to accompany Caly as she sings. You might need a tissue as you can see how much this moment means to both Caly and Rachel Platten. If you like this song then you might also enjoy watching The Piano Guys perform their Rachel Platten Scottish Cover.
