There's time for Coldplay to be back in India, but there are still some 'strings' connecting them with the country. A signed guitar by the entire British rock band will be up for sale at a charity auction - The Idea of India - hosted by actor Rahul Bose here on February 19.

According to a statement, the international band comprising Chris Martin, Jonny Buckland, Guy Berryman and Will Champion, signed and donated a very special guitar for the charity auction.

The signed guitar is the only international piece of memorabilia that will be auctioned along with 11 other pieces donated by some major and noteworthy Indian heroes and legends.

From surprising Delhiites with an impromptu gig, to meeting Prime Minister Narendra Modi and Delhi Chief Minister Arvind Kejriwal to capturing different hues of India in a song "Hymn for the weekend", the band seems to be adding more pages to its India travelogue, making it more eventful and colourful.
