small digression:
While I was re-watching the show. I saw Karthik, commenting that out of 3 songs he sang, 2 will stand for atleast 30 yrs in future. I guess the one he left out was the pudikalamamu which was my least favorite song.
The way he spoke showed his confidence. But at the same time I am surprised he said that quite bluntly. Maybe it is due to 1. slip up or 2. Over confidence and lack of humility. We all do slip up once in a while. But to say this at an early stage of career was bit surprising to me.
As an example, when GVM introduced Katrai konjam song, he said it was favorite among all good ones. That shows humility.
