WASHINGTON — If you claim to be America’s “most patriotic rock band,” you should know the national anthem.

Or at the very least, you should sing it straight up.

Bleacher Report found this video of the Nationwide Series at Daytona, where rock band Madison Rising put its own spin on the familiar tune.

Midway through, the band turned the anthem into a raucous rock jam, which didn’t go over so well with the drivers and fans.

You be the judge.
