The National debuts new song at Women's March parties

The National treated packed houses of Women's Marchers to a new song and raucous sets over the weekend in Washington, D.C. The politically active band performed at two benefits for Planned Parenthood at 9:30 Club, one with Common on Thursday and another with Sleater-Kinney and comedians including Tig Notaro and Janeane Garofalo Saturday night.

At Saturday's sold-out show, hosted by Funny or Die, Matt Berninger and crew kicked off a six-song set with new track Turtleneck, his deep vocals giving the decidedly dark tune Leonard Cohen vibes.

The sound echoed a few details the frontman revealed last fall about the impending follow-up to the band's 2013 album, Trouble Will Find Me.

Berninger told Rolling Stone the album is "about marriage, and it’s about marriages falling apart. I’m happily married, and but it’s hard, marriage is hard and my wife and I are writing the lyrics together about our own struggles and it’s difficult to write, but it’s saving my marriage."

After taking the stage, the band's Hillary Clinton-supporting frontman asked the crowd what they did the day before, on Inauguration Day.

"I watched Maid in Manhattan in my hotel room," he said to cheers.

At one point during the set, which included Bloodbuzz Ohio, I Need My Girl and Fake Empire, Berninger stumbled off of the drum set, completing a back-roll. Laughing, he blamed Planned Parenthood president Cecile Richards, who he said dared him to do something crazy.

He joined Richards and Sleater-Kinney for a rendition of Creedence Clearwater Revival's Fortunate Son earlier in the evening, which raised $130,000 for the embattled organization.
