Katy Perry and Jodi DiPiazza Sing Firework

Katy Perry was joined by Jodi DiPiazza to perform “Firework” on Comedy Central’s Night of Too Many Stars: America Comes Together for Autism Programs hosted by Jon Stewart. The star-studded event raises money for autism programs, and DiPiazza – who says Perry is one of her favorite singers – was diagnosed with autism at a young age. Perry performs a restrained version of her song, never overwhelming DiPiazza who sings and plays the piano on the popular song.
 
Night of Too Many Stars: America Comes Together for Autism Programs airs on October 21, 2012 at 8pm. Among the celebs participating are Tina Fey, Seth Rogen, Amy Poehler, Stephen Colbert, Louis CK, Bill Burr, Katy Perry, Carly Rae Jepsen, Tom Morello, Sting, Tom Hanks, Jerry Seinfeld, Julianne Moore, Seth Meyers, Jimmy Kimmel, and Al Pacino.
