Master Nissar (aaj kyon ham se pardaa hai) has mentioned that he used to play female roles. I never knew where and how. Turns out it was on stage when he played Sita.
Master Nissar (Sita) was given two general songs, in the flower garden, "jay shiv onkaaraa (aartee)", near the Ashok tree, "are raavaN too dhamakee dikhaataa kise (etc.). These songs were very popular. Nissar's voice, embellishments, and correct pronunciation, clearly was very attractive.
