NEW YORK (AP) -- Taylor Swift will pay tribute to a young cancer victim with a special song on Friday's "Stand Up to Cancer" telethon.
"Ronan" is dedicated to a 4-year-old boy who died last year of neuroblastoma. Swift wrote the song after reading the blog of Ronan's mother, Maya Thompson, who is credited as a co-writer.
According to a person familiar with the show, but who asked not to be identified because they were not authorized to speak, the song has never been performed in public. After the telethon, it will be available on iTunes; all proceeds will go to cancer-related charities.
SU2C will air on Friday, September 7 on all major networks for an hour of live, commercial-free primetime airing at 7 p.m. Besides Swift, it will feature celebrities including Tom Hanks, Julia Roberts, Gwyneth Paltrow, Justin Timberlake and more.
