In a recent tweet (December 16) Lata wrote that she sang on the Bombay Radio Station for the first rime in 1941. I found this in the Program Guide of December 1941. It says that 'Lalita' Mangeshkar is going to sing 'Mori Nindiya Gamaye' in Raag Bihaag at the Bombay Radio Station at 6:10 pm. My guess is that 'Lalita' is really jagat didi Lata.
