I found information about this OST here: http://indiafm.com/movies/audiolisting/11561/index.html
On the other hand, there's a different soundtrack with the same name with a different artist, look at the composer here:
So I guess they made a remake of this 70's movie and Anu Malik wrote the soundtrack for this remake. But I have no proof for this thesis.
If you find a release year, please add it. Then you also can add the information that this release is put out by T-Series (Proof: Look at the first link).
