Unusual Jazz number in Hindi

There's a song called "Rut Jawaan", sung by Bhupinder and composed by Khayyam for a 60s movie "Akhri Khat". Given the style of Khayyam and also Bhupinder I found this song very unique. This is perhaps one of the best jazz numbers composed for a Hindi movie. I'm sure you would be surpirsed to hear this unusual song!!
