After doing my riyaaz (singing practice) while having breakfast I was listening to this song zindagi bhar nahi bhulegi wo barsat ki raat (Im never going to forget that rainy night) as my effort to understand Raag Yaman (or Kalyan) better. While playing the song on YouTube repeatedly, I gradually began to notice how well Bharat Bhushan has acted in this song. I noticed because if you see the same sequence in some contemporary movie or music album the contrast is striking. The moment the song starts the singer goes into this maniacal trance and in the ensuing fit he or she almost swallows the mike and vomits all over. All hell breaks loose as if some inter-planetary war is going on and soon youre not sure whether you are watching a singing performance or being witness to an angry speech by one of the wrestlers of the World Wrestling Entertainment. Of course some say its like unleashing the inner you, but seriously, are you singing, or are you being tortured by the Taliban?

Then compare this song. Bharat Bhushan sings in front of a mike in a radio station recording studio. All the expressions are so subtle. He looks a bit conscious, a bit reminiscent, slightly romantic and he also seems to be putting in an effort to sing properly. Notice how when he says dil mein tufaan uthate huae jazbaat ki raat he comes forward and grabs the mike with both hands as a natural reaction to reaching higher notes (I too have this tendency to grab something sounds crude, though when Im singing higher notes). This is how you sing.
Of course Im not saying this is the only way of singing. Im just talking about enacting this particular sequence. The director has so dexterously captured the contours of the character.
