Not everyone is pleased about Donald Trump using their music at his campaign events. Just ask R.E.M. Or Neil Young.

But one famous frontman is OK with The Donald rallying support with his mega-hit.

Dee Snider, lead singer of the band Twisted Sister, says he gave Trump permission to use his classic song “We’re Not Gonna Take It” at his events.

Snider says that he and Trump don’t agree on all the issues, but the two are friends and the song itself is “about rebellion.”

Here’s what Snider told Canadian Business in a interview:

He called and he asked, which I appreciated. I said, ‘Look, we don’t see eye to eye on everything—there are definitely issues that we’re far apart on.’ But thinking back to when I wrote the song and what the song is about, it’s about rebellion, speaking your mind and fighting the system. If anybody’s doing that, he sure is. Trump and Bernie Sanders are the two extremes. They’re raising holy hell and shaking everything up. That’s what ‘We’re Not Gonna Take It’ is about. And we’re friends. I have spent time with Donald and his family. I don’t think either of us expected that we would like each other, but you know, Donald Trump is a pretty chill guy. He’s a frontman. When that camera goes on, he furls his brow, he does his thing. Off-camera he’s very self-deprecating. He makes jokes about being too orange and about his hair.

That’s one way to go about it. Snider and Trump appeared together on a season of Celebrity Apprentice. Trump fired Snider.
