Actor John Stamos will join the Beach Boys at Riot Fest in Chicago.

He will join the Beach Boys as the drummer on September 20 in Douglas Park. In a joint statement, organizers confirmed Stamos will "begrudgingly" join the festival "after over a decade of social media harassment from Riot Fest." 

 Organizers said the agreement comes with some demands by the actor, including the follow: 

1. Riot Mike, the founder of the festival, must get a John Stamos tattoo

2. A John Stamos look-alike contest must be hosted by Riot Fest

3. A local Chicago pizza restaurant must create a Greek style pizza named after and in honor of Stamos. 

Among the list of requests are a foot run, unlimited hummus served in a guitar, and Stamos masks for the crowd. Organizers confirmed they will "make every effort to complete this list of demands."   

The 2025 Riot Fest lineup includes headlining sets from Blink-182, Weezer, Jack White and Green Day, plus performances from Weird Al Yankovic, Idles, Hanson, Rilo Kiley, The Beach Boys and more.
