Martie Maguire:

We’ve talked about “March March” being one
of the hardest ones to finish. It went through many different iterations and when you’re writing a song about something from like a perspective on the world, I think it’s even more critical that you get it right. It was a heavy subject and it needed to have the appropriate heavy track, so we were willing to put in the time and headspace to get that one just right.

I mean I think everything in the video you know, Black Lives Matter and women’s rights and equal pay and Native Americans and LGBTQ and gun gun control, all of it, but I think that’s what’s cool about the song is it’s not so much about all the causes. I mean the video is and we definitely sing about certain things in the verses, but it’s really about the the listener and the person whatever it is that you’re passionate about and that’s important to you. You have that power to be an army of one stick to your guns you know do what you believe is right in your heart. unless you believe racism is in your heart, don’t don’t follow your heart on that one.

During an appearance on The Late Show with Stephen Colbert on July 16, 2020, the band shared that the song was written “two couple years ago”.

NM: “We went to the March for Our Lives in Washington, D.C., with our kids. It was so impactful for me. That’s the first time I’ve ever been in a march that large. And we weren’t there as performers, we were just in the crowds, with my little girls on my shoulders. We took a lot from that, the energy of it. We didn’t want it to be about one particular march, so on the verses we talk about different things that are important to us.”
ES: “We were always thinking and writing about that stuff, but the news kind of caught up to what we were already talking about—whether it was the #MeToo movement or what’s happening right now with Black Lives Matter. So it was coincidental in a way, but I do think those things are cyclical. They might be the newest news story, but they’ve always been there.”
NM: “You don’t need a group around you if you’re on the right side of history. We wanted to empower people who stand up for what they believe. Unless you believe in racism, then sit down. [laughs] Know what’s right, act on it, speak out, be an army of one; you don’t need to be a follower or go along with a group if you feel strongly about what’s right.”
