Billie Joe Armstrong made everyone’s day with this unexpected performance!

Hopping up on stage just to surprise everyone while a cover band was singing the Green Day song “Basket Case” Billie Joe Armstrong sang one line and tried to give the lead singer of the group her microphone back, but she wanted to perform a duet instead. Let’s just say everybody on stage was thrilled and so was every person drinking that night in the bar. Can you blame ’em?!?

Moments like this are what make music great! The conversation lives on Facebook!
