Manoj Bajpai hums lyrics of his rap song 'Bambai Main Ka Ba'

''I am not a singer and don't know singing. I respect this art and feel it is very difficult and a lot of hard work is put into becoming a singer. All I did was rhyming the words. Anubhav gave me the strength and confidence to perform it. I am happy people are liking it,'' says Manoj Bajpai on his rap song 'Bambai Main Ka Ba'.
