Topping this year's Bonnaroo surprises in WTFness was a Sunday cameo by ’80s hitmaker Lionel Richie, who joined
the already-a-fish-out-of-water Kenny Rogers for versions of “Lady” and
“All Night Long.” Though no one in the crowd would probably ever attend a
normal Rogers or Richie concert, they went nuts just the same. Maybe
they were just being sarcastic.
