Both acts were playing at UC Riverside’s Heat Music Festival in California Sunday night, and when it came time for Panic to revive their 2006's emo-rock hit "I Write Sins Not Tragedies," the guys pulled a guy out from the audience to help sing along.
Turns out, that guy was Chance.
Chance acted a hypeman for the band, as the audience collectively lost it.
Don't lie. You still know all the words.
