There were plenty of celebrities entertaining on "The Farm" this past weekend.
The annual Bonnaroo Music & Arts Festival in Manchester, Tennessee was not without surprises, and some from non-musicians. Actors Zach Galifianakis and John Hamm appeared during a 1980s-throwback SuperJam and led a singing of "We Are The World," though they weren't officially scheduled.
According to Zap2It, the duo performed earlier in the weekend in the comedy tent.
Actor Corey Feldman was also at Bonnaroo and presented a screening of "The Goonies." And comedian Ed Helms, who plays bluegrass music, performed at the festival for a song with Mumford and Sons.
After four days of camping and baking in the hot sun on the more than 750 acres of land where Bonnaroo is conducted, fans were treated to performances Sunday from Robert Plant, Florence and the Machine andBilly Joel, to name a few. The performances were streamed live online through Red Bull TV for those who wanted to watch from home — for free.
During his performance, Joel told the audience he attended Woodstock.
"I didn't play, I just went there. This is what it might have looked like," he said, looking out at the crowd.
According to The Tennessean, Bonnaroo 2015 drew an estimated 80,000 people. The website governing.com says the event is a boon for the area where it is hosted, pumping around $20 million into the local economy.
