Question: Ronan has only been performed twice, once during the fourth concert tour of her album released in what year?

"Ronan" is a charity single released on September 8, 2012, by American singer Taylor Swift to the iTunes Store.  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.  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.  All proceeds from sales of the single go to help fight cancer. <SEP>  The tour's European and North American dates, as well as two shows in Japan, were announced in November 2014, followed by the Oceania dates in December 2014.
