It’s perhaps one of Indian cinema’s most talked about romantic scenes, it’s night in Ramgarh and widow Jaya Bhaduri is slowly turning off the lights while watching Amitabh Bachchan sitting on his porch teasing a tune out of his harmonica. The scene, of course, is from cult classic Sholay, but it’s the haunting harmonica sound which sets it all up. Cut to rain-soaked Mumbai and another wind-swept song, this time from Manzil and it’s Big B again romancing Moushumi Chatterjee in south Bombay as the unforgettable Rim jhim gire saawan plays in the background. Now put the two songs on shuffle and what you have is an evening dripping with nostalgia, thanks to the Mumbai Harmonica Group, an informal coming together of lovers of the tiny musical instrument. Once a staple with Bollywood heroes, it’s sadly disappeared from the public consciousness of late.
