Good Charlotte Joined Country Headliner at Stagecoach Festival

Country star Luke Combs threw a whole lot of exciting curveballs during his headlining Stagecoach set on Sunday (April 27) and one of them was an appearance from pop-punk icons Good Charlotte.

Benji and Joel Madden hopped onstage with Combs to perform “The Anthem,” a 2003 mega-hit off their first studio album.

Even more surprising than this particular artist matchup? The (mostly) country crowd immediately understood what was going on and sang all the lyrics out loud. Combs himself did a pretty good job too, putting a bit more twang on the song than we’re used to.

Combs might be known for traditional-leaning country, but he’s got ample chops in other genres, too — a fact he would go on to prove again later in the night, when he joined the Backstreet Boys on the late-night stage to sing “I Want it That Way.”

During their time onstage with Combs, the Madden brothers returned the favor. They joined Combs for a group rendition of “Where the Wild Things Are,” naming the hit as one of their “favorite” of his songs, according to Variety.

Combs headlined the third and final night of the California-based country festival, concluding a weekend of special guest-heavy sets from fellow headliners Jelly Roll and Zach Bryan.

During his time onstage on Saturday night (April 26), Jelly Roll brought out a whopping nine surprise stars, including Shaboozey, MGK, Wiz Khalifa, BigXthaPlug and his wife Bunnie Xo.
