… sung to a single person, not an audience.
Let me explain that a bit.
Hindi cinema, especially in the glamorous and colourful world of the 60s, is full of songs inviting love (or lust, or whatever interpretation one might want to put on it). Whether it’s a Helen with bizarre eye makeup singing Aa jaan-e-jaan to a caged lover in a floor show or a floral-shirted Joy Mukherji openly serenading Asha Parekh in a Tokyo party, there’s a good bit of sizzle, lots of “Come on and give us some love”.
