Yep, according to my latest research, that’s who she is! And by the way, happy 94th birthday, Shamshad Begum!
P.S. Originally, I had labeled her as Gope’s beautiful Jewish wife, but further evidence shows that she was not actually Jewish (see comments). However, there is shot in this clip of one of the great Jewish actresses, Ruby Myers aka Sulochana (somewhere in the middle). She’s a big woman here (though maybe not as big as Latika’s husband), and she’s wearing a nice big hat. This is the best clip of this song that I have seen, and it includes very nice parts that were edited out of the version(s) that I’ve posted before.
