Bonnaroo: Watch Jon Hamm and Zach Galifianakis Sing "We Are the World"
Hamm is quite skilled at throwing gummy bears in people's mouths, as it turns out.
Jon Hamm and Zach Galifianakis are the children, apparently.
The stars were among the revelers at this weekend's Bonnaroo Music Festival in Tennessee, where they hit the stage at the start of Saturday's Superjam dance party to sing a rendition of the 1980s hit "We Are the World."
The two actors, who performed a surprise comedy set at the festival that day, each had microphones and helped encourage the crowd to take part in a sing-along.
Earlier in the evening, Hamm hopped on stage during Belle & Sebastian's set and attempted to throw gummy bears into lead singer Stuart Murdoch's mouth. Hamm and Galifianakis co-star in the upcoming Fox comedy Keeping Up With the Joneses.
Video of them at Bonnaroo can be seen below.
