Producer-director Nasir Hussain, known to be the man with a midas touch, loved to work with Asha Parekh and RD Burman, preferably both. In Teesri Manzil Shammi Kapoor wanted the music of Shankar-Jaikishan. Nasir saab urged Shammi to hear RD out. Shammi played two of his proposed songs. Shammi was sold.
Teesri Manzil (produced by Nasir but directed by Vijay Anand) is to this day regarded one of the all-time musical blockbusters of Hindi cinema, with songs like O Mere Sona Re, Deewana Mujhsa Nahin, O Haseena Zulfon Wali, Aaja Aaja Main Hoon Pyar Tera and Tumne Mujhe Dekha being hot favourites to this day.
