At the hub of this weekend’s Women’s March in Washington DC, Planned Parenthood hosted an expansive benefit concert, with Sleater-Kinney sharing the headlining bill with The National.

Sleater-Kinney brought something extra special to their set, with Planned Parenthood president Cecile Richards (as well as The National’s Matt Berninger and Dirty Projectors‘ Dave Longstreth) joining them onstage to perform the Vietnam-era staple “Fortunate Son” by Creedence Clearwater Revival.

Although Sleater-Kinney have included the anti-war protest tune in their set for multiple years, CCR’s classic perfectly fit the outspoken vibe of the day, and the special guests put a cherry on the top of an excitingly successful day of over 500,000 protesters in the nation’s capital.

Watch the performance below.
