Joe Biden has managed to attract some major league stars to perform at his inauguration concert, including Lady Gaga and Demi Lovato, but one surprise guest has the Twitter-sphere in a frenzy.
Bruce Springsteen, Justin Timberlake and the Foo Fighters have all taken to the stage for the star-studded inauguration concert hosted by Tom Hanks, but it was a rendition of Amazing Grace by famed cellist Yo-Yo Ma that has everyone talking.
Ma, 65, is arguably the world's most well-known cellists. Ma has been performing since he was 4-and-half years of age so it is not too surprising that he knocked his inauguration performance out of the park.
