The Red Hot Chili Peppers seemed to have some free time yesterday and decided to make the best of it by giving students at a California school an unexpected live performance. Costumes and all the band played their hit song “Can’t Stop” for the children and staff at Viewpoint School in Calabasas, California where the kids of drummer Chad Smith attend.

“Who Rocks out at 9:30am at my kids’ school?… we do!” Smith tweeted after their set.

The group played at the school during its Great Pumpkin Day Assembly. On stage Anthony Kiedis appeared in a schoolboy styled outfit complete with a mask. Josh Klinghoffer rocked a suit accompanied by a neon green wig and sunglasses. The bands bassist Flea danced around in a skeleton body suit while Chad Smith sported a papal outfit complete with hat and Guy Fawkes mask covering his face on the drums.

I’m sure parents of the students were kicking themselves later that day when their children surprised them with the news of what had happened at school as they got in the car. Hopefully they will kick off their middle school tour soon.
