What a breath of delight for you to remember Diwali, Sir Furry! And I thoroughly loved reading the hymn...
In Seattle, the University of Washington in the 1960's, I was dating a Ph.D. student from Pakistan, and from him I learned to appreciate the classical music of India...Ravi Shankar as well as others, were invited by the University to give concerts. I just looked up Ravi Shankar now, and learned he lived into 2012, died age 92 -- wonderful.
