question about a song sung by coal piece (chungal)

What is the name of the song sung by chungal during the end of the burglary scene?
He sings it as he is tying up the elderly parsi man.

It is translated by the subtitles as:
"Salaam to the King of Bombay, salute, my buddy
Celebrate big-city life, eat, drink and be merry "

I think I've heard this song before but I don't know the exact name of it or the movie from which it came.
Hope somebody can help me.
thanks in advance,
chumma
