Some people didn't recognize him at first - dressed casually and wearing wire-rim glasses - but when he got to the stage, they took notice of singer Huey Lewis, who joined the Big Sky Mudflaps for a couple of songs Thursday, April 11, in Hamilton.

Lewis sang and played harmonica at the free Mudflaps concert, which was in the Bitterroot Brewery. He also joined the background singers for Joan Zen's "Chain of Fools" rendition, which "tore the roof off the place."

Don Maus joined in on the bass for the Huey Lewis songs, and 'Flaps musician Chuck Florence was featured on sax, as was Steve Powell on piano.
