Thank you Rajesh! You should let Baradwaj Rangan know about these songs. According to him, "The only Hindi songs I know of hers are the ones from Akbar, the dubbed-in-Tamil version of Mughal-e-Azam, so I decided to check what else was out there. To my amazement, I found a song by, of all people, Bappi Lahiri. It’s a duet with Kishore Kumar, from a 1986 potboiler named Singhasan."
