Padosan

Bhola (Sunil Dutt) has fallen hopelessly in love with Bindu (Saira Banu), but he lacks the money and charm necessary to win her over. Instead, he comes up with a scheme with his friend Guru (Kishore Kumar), a successful vocalist: Bhola pretends to serenade Bindu, but in actuality, he's only lip-synching to Guru's singing. The plan works, and Bindu, enthralled by Bhola's supposed singing ability, falls for him, until one day she discovers the ruse.
