Female- Female Duets present an opportunity to listen to many of the voices that we listed to in the female solo songs, with a different perspective of – in terms of the subjects as well as style of singing these types of songs.
Barring an exception, I have picked up only those FF songs for which HFGK has identified the singers.

We will take up Summing Up of Duets for 1945 in the form of MY Top Duets, in the next episode.
The world is too small? or Is it? 
Ashokji,
From this list my top favourites are, not in order:
1. Naina bhar aye neer
2. Aaj hans Hans ke do do baatein ki hain sanam ne hamare
3. Ratiyan guzaarun kaise haye nindiya na aave
4. Aahein na bharin shikwe na kiye.
I hope to find them in your final list.

I have been deliberately avoiding putting the songs previously known to me in MY TOP songs. That is to make me pay for more attention to listen to the songs I have listened first time, and trying to imbibe their nuances.
Therefore, my formal list will not have my choice on the lines that you have indicated here.
I f I would have retained the selection pattern that I have been following for the years 1949 and up, my list would have mirrored yours.
