Rajesh Khanna will be an icon 500 yrs from now. With the advent of electronic media none of our videos/films will ever ever die . so even 500 years from now it will be possible to Google? Rajesh khanna and see everything like today.
At that time, we were sure that Kaka will score over all else from our time because of his values and eternal love that he propagated in his films and his immortal songs..people may? even be studying his songs like we do Shakespeare, Tansen, Thyagaraja today.
