Kishore Kumar.
He had the odd singing assignment for Dev Anand in Guide (1965) and Jewel Thief (1967) but that was all. The turning point came with Aradhana (1969).Though Burmanda used Kishore as what he called his second service, his songs for Rajesh Khanna - Mere Sapnon ki Rani and Kora Kagaz Tha Yeh Man Mera proved super duper hits ahead of the Mohd. Rafi songs for the same film. It was a second coming and there was no turning back. Kishore formed a solid hit pairing with Rajesh Khanna and in the early 70s the duo churned out hit after hit. He overtook all competition and was the undisputed number one male playback singer of Hindi films, his voice pulsing with verve and exuberance.
