What he needs is more confidence I think...the fact that he is the oldest contestant and this is as show with lots of emphasis on good looks and performances and appealing to the young audiences, he has always appeared to be on the backfoot
Suresh wadkar..one of the greats who happens to be his Guru has expressed his confidence in him...so he cant be that bad a singer..
So maybe he should just stop getting intimidated....stop saying things that he is improving and trying...and just go ahead and show his talent ( if he has some😉)
