Well, it is really understandable that he or any Hare Krishna would have this particular song/mantra very imprinted in their spyche.

This is the standard deity greeting recording that is used in all temples under ISKCON (International Society for Krishna Consciousness) instituted by Bhaktivedanta Abhay Charan. And, it is played at Brahmamuhurta, the pre-dawn hour.

As he expounded, and I presume only according to his gaudyamath disciplic section, the song would be purified or be devotional since even as celebrities they are serving Lord Krishna, by endorsing their name/fame to the mantra.

But, as explained to him by RishiDeva, he only needs to favor the ever graciously present peeling of a bell, and it will be. There is no need to concoct anything aiming for some calculated agenda or motivated interest.

He should not be surprised about that at all. Interesting though that it is not the Hare Krishna mantra, which he negotiated from 64 rounds of 108, down to 16 of: "Hare Kṛṣṇa Hare KṛṣṇaKṛṣṇa Kṛṣṇa Hare HareHare Rāma Hare RāmaRāma Rāma Hare Hare"

His own recording of japa session during an early morning walk is very popular among his followers. If not him, this reply applies to his advanced followers in succession.
