Sonu Nigam

I am right now listening to Sonu Nigam's program on Sony. This program was presented live in some 'phirangi' country (is it THE Alber Hall?). He is singing one after another great Mohammed Rafi numbers. Anyway, I am SO disappointed! I am (was, now) Sonu Nigam fan, but his rendering is so below expectations. I am sorry that I switched to this channel because now I can't move away from it and the more I hear Sonu Nigam singing these old songs, the more I am disappointed.
