Back in 2015, megastar Amitabh Bachchan had shared his experience of working with music composer Ilaiyaraaja. The musician was being felicitated at a function for completing the music of his 1,000th film. Amitabh was also present at the event. 

"I have never dared to sing in front of him because I found it very embarrassing. Every time I used to sit in a studio separately to record... I remember one occasion while doing 'Paa', where I had to sing a song with Raja saab in front of me. I can't say how frightening it was," Amitabh Bachchan told reporters during the music launch of his film 'Shamitabh', which also starred Dhanush.
