Yep, according to my latest research, that’s who she is! And by the way, happy 94th birthday, Shamshad Begum!
P.S. There is also a great shot of Ruby Myers acka 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.
