Can anyone give me the duet from film Tauheen?

Are Kasani Ji,
Gaane ke details bhi to bataaya kijiye. Kai baar movie ka naam pata nahi hota, lekin gaane ke bol padh ke gaana samajh mein aa jaata hai. Jitne zyaada details aap gaane ke baare mein de sakenge, utni aasaani hogi.....

Jags ... Tauheen mein to Guru ke sirf ek hi gaana hai. Tujhe usse mohabbat hai, a duet with Asha-ji. sahi gaana hai - Boppi-da ka mujic bhi nice hai. But it is an out-and-out Asha-ji show ... Guru ke parts kam hi hai.
yeh lijiye Kasani-ji aapka gaana

Are Sauvik bhai,
galat mat samjhiye.I was'nt angry or anything with kasaniji. lekin kai baar aisa hota hai ki we; rather I know the lesser known songs just by words and not the movie name. In such a case if we have the title of the song ,it often helps in finding the songs.was only suggesting a means for easy access...
cheers n enjoy kishoreda...always.....

Thanx Sauvikbhai
