Called "Aaj ki shaam pahloo mein tu", the seductive dance number was written by Naqsh Lyallpuri and recorded in the 1970s for a shelved film that was then tentatively titled "Rehnuma".
Composed by late Madan Mohan, the song has an alterante tune for the antara and is available on the composer's website.
Four never before heard Asha Bhosle-Madan Mohan songs were also released last year in the album "Tere Bagair".
The two have given many a hit songs like "Jhumka gira re", "Sabah se yeh kahdo", "Zameen se humen aasman par", etc.
