Rahman Hits - Varaaga Nathikaraiyoram

That is two Rahmans actually. A R Rahman the composer and his brother-in-law Rahman the actor. The song was a super duper hit of its time though the movie (Sangamam directed by Suresh Krishna) itself didn't do too well. It was A R Rahman's initial composition fully based on Indian Folk Music (with a Classical touch to it). Tamil Folk Music had until then considered to be solely Illayaraja's Territory. This movie helped to prove Rahman's versatility (if it needs any proving at all!)
