I searched you tube for the real version that was in the movie, however I could not find it. I have decided to upload it myself.
(The differences from the Dil Se movie and Inside man are very noticeable and in my Opinion this is the better song)
This is NOT the Chaiyya Chaiyya song from the Bollywood movie "Dil Se". This song was remixed for the movie Inside Man
Chaiyya Chaiyya-Insideman Soundtrack
