After much anticipation about the identity of an “unannounced closing” act at this year’s Newport Folk Festival in Rhode Island, Mumford and Sons took the stage Saturday revealing the UK band to be the surprise act at the popular music festival (and not Neil Young, Paul Simon or David Byrne). The band got into the spirit of Newport by bringing out several guests including Phoebe Bridgers for a cover of Radiohead’s “All I Need” and Newport icon Mavis Staples to perform a high-spirited rendition of the Band’s “The Weight” which you can watch here.
