During the shoot Manish told Udit that he has grown-up listening to his songs and requested him to sing 'Pehla Nashaa...' so that he could act in an archetypal style; Udit spontaneously obliged to give a voice-over.
That is not it... Manish also revealed a secret there. He fondly cherished a childhood memory that when he was a kid his Mom always made me dance at every birthday party on Udit's popular number - 'Tu Cheez Badi Hai Mast Mast'. On his request Udit & Mika were seen matching 'mast-mast' steps with him which left people on floor laughing.
