Yes, Mohd Rafi did sing for Raj Kapoor. The film was Tara Harish's Do Ustad, and it was a complete entertainer. And yes, the playback of Rafi sounded absolutely perfect in Raj Kapoor's lips. In fact, if I may say so, it sounded much better than Mukesh. So, if you ask me, Raj Kapoor should have opted for either Manna Dey or Mohd Rafi for his playback. Mukesh made him sound too melancholic, preachy and drab. There I've said it.
But, soon Rajan's grey persona surfaces. Unable to locate the Rs 1 lakh that Madhu is carrying, he offers to hand over Madhu to Jagan for a paltry Rs 10,000. Madhu overhears the conversation and is devastated. She can't imagine that Rajan would sell her. Madhu tries to escape from Jagan's den but is caught. Soon Rajan realises what he has done and wants Madhu back. In the meantime Jagan's wife comes to know the truth about her husband and is distraught. She is on the brink of suicide when Rajan saves her and takes her with him, after which he resumes his search for Madhu.
Yes, a crazy lot of things keep happening. And all this happens quite fast in the film. So there won't be any boredom. Plenty of incidents take place. Clouds of misunderstandings are cleared before they gather again. People separate and get back together again. Amidst all the bitterness what reigns supreme is the love plot between Rajan and Madhu and the awesome tracks.
While the film is absolutely a potboiler, with a social message (as like in all Raj Kapoor films) there is hardly any pontification. In fact, not much reels are spent delving into the wrongs that society did against the two brothers. The director focuses quite a bit on the development of the romance between Rajan and Madhu and that is what makes the film so enjoyable. Moreover, the time that is spent towards the end showing Jagan and his plight started getting a tad too long. Sheikh Mukhtiar, I beg everyone's pardon, had quite a grotesque face. The less shown him the better. He does act okay. But I concentrated more on the lead pair.
