I think , among the live audience, the person who was enjoying the proceedings the most on both the days (pre-finale and Finale) was Rahat Fateh Ali Khan's cute little son.
He was moving in synch with the music, aakhir beta kiska hai!
btw during kaj ra re, was abhisek asking him to come on the stage to dance? i think i saw him dancing with a kid then after that they showed RFAK sitting down with his son?? that was weird..
