Seems like Simbu prefers to be behind the screens off late. He has already proved himself to be an all rounder by trying out acting, writing, screen play, and dialogues. And now what is latest? Simbu is all set to lent his voice for composer Srikant Deva's song. Simbu has already proved himself to be a good singer by rendering songs like 'Loosu Penne' and 'Thathai Thathai'. Simbu is to lent his voice for the movie 'Adhinarayana'. The film has Gajan in the lead under the direction of Vettri Vendhan.
