Robert Plant knocked over during Buenos Aires performance

Robert Plant was temporarily knocked to the floor when a fan invaded the stage during a recent gig in Buenos Aires, Argentina. Scroll down to watch fan-filmed footage of the incident.

The stage invasion happened last Thursday [November 1] when Plant and his group The Sensational Space Shifters performed at Estadio Luna Park and had just finished performing Led Zeppelin's "Going To California". A man ran onto the stage and approached Plant but was tackled by security with the scuffle causing Plant to lose his balance and topple over.

Plant soon returns to his feet, saying: "Easy, easy" before adding "Thank you very much for the fun" in the direction of the audience.

Led Zeppelin release their live DVD Celebration Day, filmed at the band's 2007 reunion show at London's O2 Arena on November 19.

Guitarist Jimmy Page has also hinted that he will release remastered versions of all Led Zeppelin's albums in 2013.
