On Screen Singers, Bollywood Movies Songs Options

[ksmehta]

Hello everyone,
This is my first question in this forum.

We listen and/or watch many Bollywood songs.
Is there any Web site, any one knows, which will tell us the name of an actor or actress on screen who sings the particular song.
Many a times, some beautiful songs by Rafi or Mukesh or Mannadey are heard and seen in the movie but in some cases, the singer on the screen is rather an unknown extra or a secondary character.
Any help for such a link will be appreciated. Thanks.
