TO WHOM IT MAY CONCERN
This is to certify that Sri Chandrakant Prabhakar Sardeshmukh alias Chandu had been learning Sitar with me since his childhood from 1963 but when I started touring abroad he began taking lessons from my wife Smt. Annapurna Ravi Shankar and continued till 1976. He is a very promising and talented sitar student. I wish him all success in his life.
