text: According to music and film expert Rajesh Subramanian, "Aap Ke Haseen Rukh" (from Baharen Phir Bhi Aayengi) was planned with full orchestration but many of the musicians were late for the recording. After a disagreement with Mohammed Rafi, Nayyar began working with singer Mahendra Kapoor. Kapoor performed Nayyar's song "Badal Jaaye Agar Maali, Chaman Hotaa Nahi Khaali" in Bahaaren Phir Bhi Aayengi. Based on a Bengali language work by Rabindranath Tagore, Nayyar composed "Chal Akelaa, Chal Akelaa" (sung by Mukesh in 1969 film Sambandh).
  Nayyar co-produced songs with Shamshad Begum (including "Kajra Mohabbatwala"), and after Madhubala's 1969 death Vyjayanthimala, Sadhana, Mala Sinha, Padmini, Asha Parekh and Sharmila Tagore lip-synced several Nayyar-Bhosle songs. Nayyar and Bhosle parted ways in 1974, and he then worked with Dilraj Kaur, Krishna Kalle, Vani Jayaram and Kavita Krishanmurthy. Majrooh Sultanpuri and Sahir Ludhianvi wrote the lyrics for some of Nayyar's earlier songs, including "Naya Daur". Nayyar also worked with developing lyricists such as Jan Nisar Akhtar, Qamar Jalalabadi, S. H. Bihari and Ahmed Wasi. He began the tradition of assigning full, three-minute songs to comedians. Om Prakash sang Nayyar's "Churi Bane Kanta Bane" in Jaali Note and Eent ki dukhi paan ka ikka in Howrah Bridge and Johnny Walker sang "Aye Dil Hai Mushkil Jeena Yahaan" in CID, "Jaane Kahan Mera Jigar Gaya Jee" in Mr. & Mrs. 55, "Main Bambaika Baaboo, Naam Meraa Anjaanaa" in Naya Daur and "Bajewala" in Basant.
