"Ronan" is a charity single released on September 8, 2012, by American singer Taylor Swift to the iTunes Store. Swift's lyrics are based on a blog she read about a four-year-old boy, Ronan Thompson, who died from neuroblastoma in 2011. Swift wrote the song by putting together quotes from blog creator Maya Thompson, Ronan's mother. Thompson is credited as a co-writer of the song. Swift first performed the song live for Stand Up to Cancer in September 2012, and has only performed it publicly one other time, at the Glendale, Arizona stop of The 1989 World Tour, at which Thompson was in attendance. All proceeds from sales of the single go to help fight cancer.
