The News Minute | February 07, 2015 | 01.20 pm ISTProbably a tune that anyone in India with some kind of access to a mobile phone would recognise, Airtel’s signature tune composed by AR Rahman is ubiquitous.An old man, a street performer sitting outside a temple began playing an almost exact replication of the tune using just a simple string instrument in a Facebook video shared by the maestro himself.One thing is for certain: talent can be in any form, developed at any age, and can be found in the most interesting places , where we might least expect it. Also, pay close attention to the end of the video, where he begins playing a certain hit Tamil single that went viral across the world. Post by A.R. Rahman.
