Would anyone complain if Mumford & Sons did this at the iHeart Festival this weekend?
Earlier this week - after the bands opener called in sick - they decided to put on costumes and open for themselves
The new band was called: "The Sun Never Sets On The Cool Kids."
Here's what they played:
"You Shook Me All Night Long" (AC/DC cover)
"You Really Got Me" (The Kinks cover)
"Wagon Wheel" (Old Crow Medicine Show cover)
"The Weight" (The Band cover)
"Girls Just Wanna Have Fun" (Cyndi Lauper cover)
"Atlantic City" (Bruce Springsteen cover)
