Anthony Kiedis played with the Red Hot Chili Peppers at last night’s (April 13, 2016) gala at the Sean Parker and The Parker Foundation Launch for The Parker Institute for Cancer Immunotherapy Gala in Los Angeles. Apparently they played Can’t stop, Otherside, Californication and By The Way.
I’ve just embedded a selection of photos- there are looks more on the Getty Images website
(Many thanks to my friend for the information).
