The Red Hot Chili Peppers drummer stated how they raised a lot of money for charity that night, and how they did an event in Seattle together. Chad put a little band together featuring Mike McCready (Pearl Jam) and Duff McKagan (Guns n' Roses, Velvet Revolver), Stefan Lessard (Dave Matthews Band) and country / folk singer Brandi Carlile, while Will came up and played cowbell. Chad Smith reveals:

"I can't really expound upon details, but we have been talking about doing something next year that will combine music and comedy - a show. It will benefit the charities we're into. Plus, I think I need to redeem myself from how I was robbed of the Golden Cowbell."

The duo may even bring a third kind-of doppelgänger into the mix with Metallica drummer Lars Ulrich.

Here's the video from Will and Chad's battle for the title of greatest drummer on the Tonight Show that ends in a surprise performance of Don't Fear the Reaper from the Red Hot Chili Peppers:
