AceShowbiz - Taylor Swift was a surprise guest at The Civil War's sold-out concert at the Ryman Auditorium in Nashville. The 21-year-old singer helped duo Joy Williams and John Paul White perform "Safe & Sound", which was recorded by the threesome for movie "The Hunger Games".
Before Swift came up to the stage, Paul jokingly said, "We like to give back to the community, and to people [whose] careers are struggling a lot more than ours." They then tried to trick audience into believing that they had an up and coming artist who "hasn't had much time on stage" and "is really new at writing songs" as a guest.
Wearing a yellow dress and putting her hair in a bun, Swift emerged from the side of the stage and played along by pretending to be a shy girl and timidly stepping into the spotlight. After exchanging pleasantries with the band, she gushed, "Man, this is so sold out right now - do you know that?" She added, "You guys are really good."
