Rocker Robert Plant was knocked to the ground during a gig in Argentina on Thursday (01Nov12) after a fan stormed the stage.

The Led Zeppelin star was performing with his band The Sensational Space Shifters in Buenos Aires when an overzealous concertgoer jumped over the security barricade as the group wrapped up its rendition of Led Zeppelin's Rock and Roll.

A guard quickly rushed the fan, inadvertently pushing Plant over, but the shocked 64 year old was not hurt and in video footage of the incident, obtained by, the singer can be heard pleading with security to let the fan off lightly, saying, "Easy, easy."

It appears the incident didn't mar Plant's enjoyment at the Estadio Luna Park - he later told the crowd, "Thank you very much for the fun."
