It started out just for fun, but celebrity doppelgangers Chad Smith and Will Ferrell have parlayed their pairings into quite a charitable windfall. Since agreeing to a "drum-off" on The Tonight Show Starring Jimmy Fallon, the pair have staged a handful of benefit performances and they'll continue that string with a new date in Los Angeles.

The Red Hot Benefit Comedy + Music Show & Quinceanera is set to take place April 29 at the Shrine Auditorium in Los Angeles, providing those in attendance a night of music and comedy. On the music side, Smith's Red Hot Chili Peppers bandmates are set to join him for the night. The comedy lineup has yet to be revealed but Ferrell and the comedy site Funny Or Die are booking the talent for the evening. As with past collaborations between the pair, proceeds raised for the show will be split between Ferrell's Cancer for College organization and the Silverlake Conservatory of Music which has ties to members of the Chili Peppers.

"I have only one great regret in life and it’s that I never actually celebrated my quinceanera,” said Ferrell. “I’d like to think it was just a simple oversight by my mother, but there has been a void inside me for many years. Growing up on the mean streets of Irvine, Calif., I have vivid memories of all my friends celebrating their quinceneara. Well, on April 29 at the Shrine Auditorium, with the Red Hot Chili Peppers and a bunch of other really talented comedians and musicians by my side, we are going to right that wrong, and everyone is invited."

“We had so much fun with Will on the drum off and ultimately getting the entire band together to participate on the Tonight Show," said Smith. "So much goodwill came out of one silly joke. We’ve been trying to find another way to get together and do some more good for our respective causes and I think we have found it. I’m going to check with my own mother, because I don’t recall any family photos of my own quinceanera either."

There will be a limited ticket pre-sale beginning Tuesday (March 8) at 9AM PT, followed by general ticket sales beginning Friday (March 11) at 10AM PT. Citi customers can take part in Tuesday's pre-sale at this location. All ticketing info can be found via Funny or Die.
