tu mera chaand
main teri chaandni
main tera raag
tu meri raagini

tu mera chaand
main teri chaandni
main tera raag
tu meri raagini

ho nahi dil ka lagana
koi dillagi koi dillagi
nahi dil ka lagana
koi dillagi koi dillagi
saath hi jeena
saath hi marna

ulfat ki hai reet
haan ulfat ki hai reet
saath hi jeena
saath hi marna
ulfat ki hai reet
haan ulfat ki hai reet

pyaar ki murli har dum gaaye
teri lagan ke geet
pyaar ki murli har dum gaaye
teri lagan ke geet

main tera raag
tu meri raagini
tu mera chaand
main teri chaandni
main tera raag
tu meri raagini

bhool na jaana
rut ye suhaani
ye din aur ye raat
haan ye din aur ye raat

bhool na jaanaa
rut ye suhaani
ye din aur ye raat
haan ye din aur ye raat

jab tak chamke chaand sitaare
dekho chhoote na saath
jab tak chamke chaand sitaare
dekho chhoote na saath

tu mera chaand
main teri chaandni
main tera raag
tu meri raagini

ho nahi dil ka lagana
koi dillagi koi dillagi
