Jisane todi khaamoshi kaun hai
Jisane todi sarghoshi kaun hai
Dheeme dheeme kaano mein hai bolata
Tere dil ke darwaaje hai kholata
Usaka kehana hai na rehana dare dare


Karthik karthik calling karthik
Karthik calling karthik
Pick up the phone, pick up the phone….


Jo karata hai mujhase baatein kaun hai
Mera hai meri raatein kaun hai
Kaisi meri yeh ulljhan hai kya kahun
Chain ka woh dushman hai kya kahun
Nind hai inn aankhon se pare pare


Whose on the line tell me whose calling
Whose on the line tell me whose calling
Karthik karthik calling karthik
Karthik calling karthik
Pick up the phone, pick up the phone….
Karthik calling karthik.
