Once Don was completed, it had problems getting a buyer. After the trial show, Javed Akhtar suggested Chandra Barot to insert a dance number in the second half, which otherwise was looking quite heavy and dry. The song "Khai Ke Paan", earlier rejected for Dev Anand's Banarasi Babu (1973), was recorded and inserted completely out of context in this film. And the rest is history.
