Narayan and Rathod rendered it

Heeralal Pannalal released in 1999.

My collection contains just one song from the film.

It was titled Ekka Dukka Tiya Du, and it happened to be the title track of the film.

The two men who lent their voices to the song were Udit Narayan and Vinod Rathod.

Incidentally, they were the voices of the soundtrack.

The song was picturised on the titular characters, Heeralal (Mithun Chakraborty) and Pannalal (Johnny Lever), and its title was their takiya kalaam*.

Shaheen Iqbal wrote the Anand Raaj Anand composition.

(*Note: Takiya kalaam is the Urdu word for, “Catchphrase”)
