The crowd in Argentina was in for one hell of surprise this past weekend, when Robert Plant came out to sing some classic Led Zeppelin.

Jack White was playing this past weekend at Lollapalooza Argentina. Jack White has occasionally thrown some Led Zeppelin songs in his set list from time to time. So the crowd was not shocked by this, but who joined him on the stage next was the shocking factor.

Led Zeppelin front man Robert Plant to sing the lyrics to 'The Lemon Song'. The last time Led Zeppelin had a show was in 2007, but Robert Plant has been known to bust out some Zeppelin songs since then. Also that last time this particular song was played live was 1995 in Norway.
