Among the music composers, Rafi was out of favour with Anil Biswas, Salil Chaudhaury and RD Burman. Anil Biswas condescendingly used Rafi's voice in the movie Heer. Salil Chaudhaury was a little more generous than that ! Maya and Madhumati had some immortal songs in Rafi Saab's voice. But in Us ne kaha Tha, Ch aaya, Do bheega zamin and Jaagte Raho, Rafi was given the less humble numbers. Nowhere is this bias more pronounced than in Kabuli Waala. Rafi had to be contend with 'Aye Saba kehna mere dildaar se'. To his credit, he pulled off the Pashtun accent with great panache.Today, everyone gushes over the RDB/ Kishore Kumar partnership. But, what is less commonly known is that, when RDB got his first independent film as a composer for Mehmood's Chota Nawab, he turned to none other than Rafi. Good for him that he did so ! Probably, he did not believe in taking any chances with his career. Remember that song' Ilaahi tu sunle hamali dua' by the immature chote nawab-Mehmood, who is pleading for the life of his dying father ? The song is so moving, that it cannot, but touch to the core of one's heart. Why, it could bring tears to even a tyrant's eyes ! That was the effect produced by, Rafi's voice and way of singing. Listen closely to the words ; it is hamaLI and not hamaRI dua. That's because the spoilt chota Nawab, had a pronounced LISP in his speech, in the first half of the movie. And Rafi Saab, had sung it LISP AND ALL, with AMAZING DIGNITY ! Could anyone, but Rafi have ever taken this song to the height of sensibility, as it is now ? Impossible!
