Apart from articles on music, he has written poetry, lyrics and even a number of stories in Tamil, that were published in Ananda Vikatan.

When I learnt that the producers of the new film were planning to have him as the hero, I knew that I stood no chance of being considered for the role," wrote MGR about V.V.

He acted as the main actor in the Tamil film Nava Yuvan (Modern Youth) that had an alternate title Geethasaram (Essence of Gita).

[7] Teaching music to children was a subject important to Sadagopan and he launched the Tyaga Bharathi, a movement to carry out his mission.

They are not nursery rhymes, but penned and tuned to Carnatic music with the objective of moulding children," said Devika Raman, daughter of Sadagopan.

When Soundaram Ramachandaran, a Minister in Jawaharlal Nehru's Cabinet, launched the Gandhigram Rural Institute (GRI), she appointed Sadagopan as the Director of Music Studies.

Srirama Bharathi is one of his disciples with whom he brought out a book called ‘Spirals and Circles’ that explains the concept of carnatic music and thought processes associated with it.

A trust called Sri Sadagopan Thirunarayanaswami Divya Prabhanda Patasala started in the singer's name.
