Sunday night saw Mumford & Sons return to the stage for the first time since bassist Ted Dwane underwent emergency brain surgery. The band headlined the main stage during the final evening of Glastonbury 2013, and closed their performance with a cover of The Beatles' "With a Little Help From My Friends." It wasn't just Mumford and co., though, as they were joined on stage by members of Vampire Weekend, First Aid Kit and The Vaccines. Closing out the festival with a little help from their friends. Appropriate.
