Story Behind the Song "Chalo Dildar Chalo"

This immortal song from Pakeezah(1972) was originally a solo sung by Lata Mangeshkar, intended for use as a dancing number, the fascinating solo version was cut from both the film and record released, later a romantic version, a duet was recorded. You may have noticed it or not, Rafi sab has sung but just a single line in it which is the Mukhda. Amazing how a single line sung by Rafi sab had made it an immortal Rafi song.
This was the only song in this film having a male voice. All the other songs were female solo. The music of this film was given by Ghulam Mohammad. He composed a total of 15 songs for the film out of which only six were used. The remaining songs were released in 1977 in an album called "Pakeezah Rang Barang". This album was released exclusively by Saregama in 1977.
This film took 16 years to complete. The mahurat of the film happened on July 16, 1956, and the film got released in Feb 1972. The music of the film was recorded by the end of 1959. Kamal Amrohi wanted this film to be a musical so 15 songs were recorded earlier.
The shooting of the film was halted in 1964 due to mutual differences between lead heroine Meena Kumari and her director-husband Amrohi. In 1968, the composer of the film passed away. So, when the film was revived in 1969, Naushad was roped in to complete the background music for the film. Many exhibitors suggested Kamal Amrohi change the music according to the then-popular trend and style. To this Amrohi said that he would have readily done this if only Ghulam Mohammed was still alive but now he cannot betray a man, who gave him such melodious songs, after his death. So he kept his music intact but used fewer songs as planned to keep up with the fast-changing trend.
In 1969 the shooting of the film resumed after a gap of five years. By this time Meena Kumari's health got deteriorated. She was suffering from Liver Cirrhosis. Few songs were yet to be picturized. Her condition became so bad that during the filming of the grueling emotional Mujraa “Teer-e Nazar,” Meena Kumari collapsed.  Keeping in mind her medical condition, a body double was brought. Actress Padma Khanna played her body double in this song as she was an adept Kathak dancer which was an urgent requirement of the song. Meena Kumari personally trained her for the scene, and the song was filmed with the majority of the dancing done under a veil in order to hide her face. 
Similarly in this song too Padma Khanna acted as Meena Kumari. Her face was actually never shown in the song.
