Well guys there is a Noor Jehan & Chorus song which I have on a tape since long and love it a lot. But sadly have no details with regard to to film, year, MD or poet. To me it seems to be of late 1960s. The song is very refeshing and catchy, Noor Jehan sings half a line and as she is singing, the chorus follows in between with the second half of the line. The song goes as-Nainon Mein Rang Layii
Dil Mein Umang Layii
Aayii Jawani Mastanii
Ho Bachpan Chala Gaya
Chan Chan Chan, Payaliya Chanki
Ho Jagii Hai, Umeed Milan Ki
Din Gin Gin karkar Biit Rahe Hain
Aas Lagii Hai Ik Saajan Kii....................
It conveys the phase of life when the innocence of childhood begins to fade away and adolescence sets in, where all relations and worldview are defined and thus starts a search for a soul mate. Many songs lament the passing of the childhood innocence but this one focuses on joys promised by adulthood.
