Oru Kadhal Enbathu - Chinna Thambi Periya Thambi
This movie Gangai Amaran is credited as the MD,but then if you hear the bass line and ludes that Ilaiyaraja stamp cannot be missed..Recently GA clarified that this song alone from the movie was done by IR but his name didnt appear in the credits..Check out the video where he says such a sound can be produced only by the Maestro ..
