The Rolling Stones gave fans a rare treat on the first leg of their South American tour on Wednesday night by playing their 1967 hit 'She's A Rainbow' for the first time in almost two decades.

Hours before taking to the stage at the Estadio Nacional in Santiago, Chile the band asked fans to choose which track they would most like to hear for the request portion of the show. Fans attending the show were then able to vote via the bands website.

Fans were given the option to choose one of four tracks that they rarely play live, 'She's a Rainbow', 'Anybody Seen My Baby' 'She's So Cold' and 'Like a Rolling Stone'. 'She's A Rainbow' won with the most votes and fans were treated to it only six songs into the set.

It was the first time The Stones have played ‘She’s A Rainbow’ which appears on the 1967 LP Their Satanic Majesties album since 1998 and only the 11th time in the bands 50-year history it has ever been played live.

The Stones continue their South American tour with three nights in Argentina starting on Sunday February 7th. The South American leg of the tour is expected to finish on March 17th in Mexico City.
