Singer himself says in one interview that Elayaraja did not call him subsequently after one incident. Singer was also acting in films in charector roles at that time and was in the shoot till 2 am. After that he rushed to Music Studio of Elayaraja in the morning. His voice was very weak as he didn't sleep properly in the earlier night as he was busy shooting with Prem Nazir , the earlier night till 2 am. Elayaraja was unhappy and told him to choose between singing and acting. Don't try to travel in two boats at the same time. The duet song was Thenral Ennai Mutham ittathu . After that last song, he did not get any call from Elayaraja, not he went and approached him. Big people, sometimes tough rules and they don't give second change. I love his voice very much , even his last song was very good, even though he did not sleep the earlier night and got firing from Elayaraja.
