Kiss bassist Gene Simmons took a tumble while performing with the band in Bozeman, Montana, at the weekend.
Video footage shows Simmons, 66, stumbling and falling on to his backside as the band run through a performance of Rock And Roll All Nite. It was captured by YouTube user Charlie Mulluk and can be viewed below.
A roadie rushes to his aid and helps him back to his feet. Simmons appeared to suffer no lasting injuries as he is seen immediately returning to his position at the microphone to address the crowd.
Kiss frontman Paul Stanley recently said Kiss could make a new album, but admitted he knows fans would only tolerate new music rather than demand it.
The band are on the road on their Freedom To Rock tour.
