According to Rahman, the film and the commitment shown by the team has reaffirmed his faith in cinema.
Rahman, who loved the track, reposted it on his Instagram, giving the badge of approval to his fellow composer.
While the step is definitely a milestone for Indian cinema, some have questioned the dependence on AI for recreation of the voices of the departed singers.
A visibly happy Rahman captured the surprise performance on his mobile phone.
The Oscar-winning composer spoke to students at an event organised by the Oxford Union Debating Society.
Rahman has composed the music for 'Aadujeevitham' directed by Blessy.
In the statement, the makers said they had deep respect for the original composition and had made the alteration as the agreement permitted them to use the lyrics with a new composition.
The controversy began after the litterateur's family alleged that the rhythm and tune of the original song were distorted.
The 'Deewana Tera' singer wondered how Rahman could create such a mediocrity as ‘Chiggy Wiggy’ from the film 'Blue' (2009).
Rahman's legal notice, addressed to the Association of Surgeons of India, demanded the withdrawal of the complaint within three days.
