Forget JazzFest, RibFest, Lollapalooza and All The Rest. The Musical Event of the Year Happened on the Tonight Show Last Night!

There are big musical events planned like RibFest, JazzFest, Lollapalooza and some of the monster summer tours, but nothing compares to the event of the Tonight Show with Jimmy Fallon last night as look alikes Will Ferrell and Chad Smith of the Red Hot Chili Peppers came on the show to square off in an epic drum battle.

The pair showed up on the program in matching black leather jackets, Kiss T-shirts, sneakers and blue baseball caps worn backwards, and sat down with Fallon to discuss the history of their "feud" -- with each speaking as the other person.

Asked by Fallon if he remembered the first time he heard about his "impostor," Ferrell -- speaking as Smith -- replied, "Yeah. I was jammin'. I was jammin' with the Chili Peppers, with my guys. At our jamhouse. I'm like, 'Flea, this is bull. I'm tired of not getting enough respect as Chad Smith. I'll be honest, I'm a little high right now."

Watch the interview above and the drum-off below. I somehow found even more respect for Smith following the show. What a great sport.
