Remake of Paper Moon.
Ek Main Hun, Ek Tu" in DARLING DARLING (1977) and "Kahoon Kya, Tumse Apni Daastan" in GINNY AUR JOHNY (1976) sound the same.
The non filmed song "Assalam Alaikum" from Apradh,was later partly sampled by Rahul Dev Burman for the song "Ek Main Hoon Ek Tu" for Darling Darling. At 0:59 of the song "Assalam Alaikum" when Asha Bhosle sing's "Al Naseeb,Al Habib", the tune at that part was the exact same as 0:45 of the song "Ek Main Hoon Ek Tu" from Darling Darling. The part when Asha Bhosle sings "Hum Tum Mein, Huuuuuu, Halka Parda Chaiye". Another song which sounded similar was "Kahun Kya Apni Dastan" from Ginny Aur Johnny. The part where Mohammed Rafi says " Tere Dil Mein Jo... Qaid Hain..".
