It was another Mangeshkar solo

Bhai-Bhai released in 1956.

Lata Mangeshkar’s voice was the main one on the soundtrack of the film.

And by no means would it be incorrect to state that that was a big deal, given the fact that Kishore Kumar was one of the titular protagonists in the film.

By the way, he sang just a couple of tracks in the film.

Coming back to the Mangeshkar solo in question, its title had three words that many people would relate to – Kadar Jaane Na.

The song was written by Rajinder Krishan, and composed by Madan Mohan.
