ohhhhhh acha. yes thats true professional singers do pronounce words correctly (and that reminds of my name is khan where in the movie srk used to say its khan not kahn :D)
also as a kid when i used to watch partition movies/dramas i used to think anyone who can pronounce khe is a muslim and whoever says kha is a hindu…hahahahahahhaha quite stupid thinking i used to have lol
ps. really? i thought amitabh speaks fine urdu as in i have never seen him saying j to z or z to j. hang on what is poorbi language? any audio or video sample?
