if Raja knew that there is something missing from the song, he would have fixed it, isn't it?? i believe Raja really didn't know that, but HR has been looking for an oppurtunity like this from a long time, so he didn't want this to miss where he got the best chance to break down Raja.
i believe Raja was already nervous that day.. don't know why?? may be his previuos performance had not been very easy, singing in female-male both voices, & most of all his outfit.. it's not easy to get on to stage with that get-up, is it?
HR was right in saying that a singer at this level should come to know how the singer has sung..... tht means if Raja did not know how he has sung.... he cant be a playback singer......
its like doctor's dyalisis 😛
