Its not about who is Ahmad zahit's fan, if that's the case then there are alot of them who can sings. I think it has to be more os the state of mind in feeling & understaind these songs, which would come across the singing
If I should sing in such a great event I would at least try to learn the poems first. Then I will dear to sing. This guy has nice voice but it is a pitty that he has never memorized any poem correctly.
