RD Burman's 1 song that for me stands out against all the rest ::::
Mere Naina Sawan Bhaado---by Kishore Kumar ( from the movie: Mehbooba)
There are two versions of this song:-
one is a solo by Kishore kumar and the other is duet by lata mangeshkar and kishore...
The story behind this song-- when RD Burman first explained the whole song to Lata And Kishore....kishore refused to sing saying its next to impossible for him to sing this song ( its that difficult for him) ..till this time there was supposed to be only the duet version in the movie...RDB then recorded a small piece of the song with LAta, gave it to kishore to practice, and after a week the duet was finally recorded...RD was so impressed with the way kishore performed that duet that he even made a solo version for kishore...
