I'm glad Tony Smith has now produced an audio slideshow of his work during the Kolkata's Cult of Durga Photo Expedition/Workshop. The software he used to produce it is ProShow Producer, rather than SoundSlides that I normally use on my workshops. His audio slideshow is divided into chapters or segments which coincied with the different phases of the Durga Puja festival.
Tony is an Associate member of the Royal Photographic Society, and he traveled to Nepal, Bhutan, India, France, China, Spain, Morocco the USA and Canada and the West Coast of Ireland. He has attended Hindu, Christian, Muslim, Buddhist and Gypsy religious and secular festivals..
He worked quite hard during the Kolkata's Cult of Durga Photo Expedition/Workshop to produce his audio slideshow on the festival; however and much to my disappointment, he has not added to it his narrative skills which are enhanced by his precise enunciation. Perhaps that'll happen in a forthcoming iteration?
In the meantime, I suggest you view his blog entry on his experiences at the Durga Puja during the workshop, which also has a number of his photographs of the festival.
