One of my friends says that the song, " Ek shahenshah ne banwa ke haseen taj mahal ", from film " Leader" is sung by Mohd. Rafi and Suman Kalyanpur and not Lata Mangeshkar.
He claims that he is 100% right saying that he himself heard Naushad in a Radio interview that the song was sung by Suman. I insisted that it is Lata Mangeshkar and not Suman. Because I have an audio cassette of Leader in which Rafi and Lata's names are mentioned as the singers.
Can somebody pls clear the doubt?

It was the song of Palki Yaar. Leader mein to Lata ji hi hain.

Song: Dil-e-betaab ko seene se lagana hoga, aaj parda hai to...
Rating: *
Singer(s): Rafi/Suman Kalyanpur
Movie: Palki
Year: 1967

Like Annu Malik, Naushad ke bhi kayi songs ek jaise lagte hain , but
original

Are you 100% sure chintu ji...... that the said song, Ek shahenshah ne banwa ke haseen taj mahal is sung by Rafi and Lata?

Ek Shahenshah Ne Banwaake - Rafi, Lata - Leader - 1964 - Dilip Kumar, Vyjayanthimala

Your confusion will be cleared when you listen to the female voice at its highest pitch in the song.

Damn dama Damn Damn sure

Ab ye mat kehna Sehra ka gaana

Pankh hote to ud aati re ->high pitch par...............................
