Krishna kumar is one of my favourite singers. He is capable of singing any type of songs. Born in kerala and brought up in Delhi, his singing in telugu and tamil without a hint of other accents is amazing.
Me and my friend Prad would always discuss which is his first song in tamil. First what i thought was his earliest song is Poovukellam siragu mulaithathu from Ajith movie Uyirodu Uyiraga. Then i found that he has sung even before in Prabhu Deva movie VIP - Eechan kaatu. Recently, when i was hearing Minsaraa kanavu songs. It suddenly struck me Strawberry kannae was KK's voice.
So as per current standings, minsara kanavu leads the pack as his earliest song in tamil.
