John Stamos reunited with the Beach Boys and brought the house down.
Stamos — who has been a regular at shows in the past — performed at the L.A. County fair for the first time since his post DUI rehab stint in July … and he looked better than ever.
Stamos has been killing the game recently — with both “Fuller House” and “Grandfathered” in production.
The Beach Boys welcomed him back as images of Uncle Jesse flashed on the big screens … right before he lit up the crowd with a sick drum solo.
Have mercy.
