But, for once, something that inspired geniuses from Kipling to Amrita Shergil to Prithviraj Kapoor to K.N. Saigal — who started off as a musician in its pit — was not allowed to die.

Twenty-five years later, it’s done, opening with a Kathak recital. History, decay, private enthusiasm, government effort: a route that could well be duplicated elsewhere.
