Chaand se chamak uthoge ek din
Will you forget me then?
How I can? Tell me how I can?

Ek din tum bahut bade banoge ek din
Chaand se chamak uthoge ek din
Will you forget me then?
How I can? Tell me how I can?

Maan lo kahin ki shehzadi
Baithi ho tumhare liye aankhein bichhaye
Aur use yeh zid ho ki woh shaadi
Kisi se na karegi tumhare sivaaye
Will you forget me then?
Yes I can? If only you can?

Ek din le gaya tumhein jo koyi ajnabi
Ghair ki jo ho gayi ye zindagi
Will you forget me then?
Gentleman, oh no gentleman!

Saans saans mein tumhari kushbu
Kis tarah jiyunga bolo tumko bhula ke
Dil pe jaan pe kar chuki ho jaadu
Jaanti ho poochhti ho phir bhi sata ke
Will you forget me then?
Gentleman, sorry gentleman!
