On a Bonnaroo weekend that has been stuffed to the brim with people joining other people on stage for special performances, Mumford & Sons got in on the collaborative fun with an all-star summit of their own last night (June 13): For their performance of the Beatles' classic "With a Little Help From My Friends," they were joined by members of My Morning Jacket, the War on Drugs, Hozier, Dawes, actor Ed Helms and photographer Danny Clinch. Check it out below:

Over Bonnaroo's first three days, Kendrick Lamar and Chance the Rapper joined Earth, Wind & Fire on stage, while Chance the Rapper also took part in a Superjam with Zach Galifianakis, Jon Hamm and a bunch of others. Hamm, meanwhile, was also seen feeding gummy bears to Belle and Sebastian's Stuart Murdoch during their set.

Although this year's Bonnaroo is only a few hours from being over, there are still performances left tonight from Florence + the Machine, Caribou, Robert Plant and Billy Joel, among a few others. Check out the remaining schedule here, and catch up with our daily Bonnaroo coverage here.
