Weezer sure know how to throw a party, and on Thursday the guest list included rapper Chamillionaire, pop songstress Sara Bareilles and ... smooth-jazz king Kenny G?

Yes, you read that correctly.

The unlikely cast of characters assembled in Beverly Hills, Calif. -- the setting for both AOL's West Coast studio and one of the band's biggest hits -- to tape Weezer's five-song Sessions in support of their new album, "Raditude."

"I don't know anything about Weezer -- nothing," Kenny G, who's sold 75 millions albums worldwide, admitted to Spinner. "I've heard the name, but I never knew any of their songs [except] some song about a sweater ... with the wool coming apart?" (via Spinner)
