I am happy to report that I have started a webpage on him on my website, with help and encouragement from his son Kailash Surendranath.
I have recovered some material from a defunct site.
So far I have added some photos and more than 100 songs.
Your feedback is greatly appreciated.
PS: If you have some material, audio, books, magazines, newspapers (NOT FROM THE INTERNET), I will be glad to consider it.
