Udit has sung for many Indian movie stars. For example, last year's Omshatiom. It's also a movie starring Chaluk Khan, with Udit as the backup singer. The song is great, I recommend it to you!
Other films he sang for Sha include Love Without Borders in 2004, Bollywood Life and Death in 2002 and Anger and Hatred in 1997.
This song is from Love Story, and its name is Ankenkuli. You don't have to watch this movie on Love Word Road, but you must listen to the original sound. Very, very good.
You can give me your email address if you like. I have the soundtrack of this movie. You can share it with me.
