South American rock enthusiasts attending Lollapalooza Argentina were treated to a very special live collaboration on Saturday night as Robert Plant joined Jack White during his headlining set for a run through a Led Zep classic.
They played 'The Lemon Song', the first time Plant had sung the song live in 20 years.
Watch it below.
White and Plant previously performed live together during two White shows last year and with the two set to play Lollapalooza Brazil March 28 and 29, it is possible they'll do it all again this weekend.
Plant declared his fondness for the former White Stripe in a Facebook interview last September, saying: "I love Jack White's buccaneer spirit, and the way he dodges through the musical horizons. I'd be happy to make a single with him."
It is thought Plant may record The Phantom's 'Love Me' at White's Third Man Records this summer.
