Taylor Swift gave fans a sneak preview of what to expect from her on Super Bowl Sunday. The singer released a video of her rehearsal session where she performed an alternate version of her latest single. Swift took her track “I Don’t Wanna Live Forever” and gave it an acoustic makeover. The song, which will appear on the soundtrack for the upcoming film Fifty Shades Darker now has a more mellow vibe to it. The video shows Swift in her practice space playing the song solo. As she strums her acoustic guitar, she sings the lyrics in the empty room allowing the echo to give the song a more melancholy vibe. Swift will be performing the Super Bowl halftime show as part of her multi-year deal with AT&T. The game airs Sunday February 5 at 6:30 p.m. ET. Copyright(c) 2017 RTTNews.com.
