Lyrics:

Baby, when you're far away from me
call me up on my cell phone
I feel your vibrations come through the phone
right into my heart
If you wanna be my caller I'm
pleased to be your receiver
I know when my favorite-melody sounds
that you're on the line

[Chorus:]
Suddenly, suddenly
Something happened to me
suddenly you appear with the key to my heart
Suddenly, suddenly
Something came over me and
you set me free - You're
The key to my heart [2x]

Until you are here with me again
I don't mind being your call girl
If you are alone, just lay yourself down
in my answering-machine
You know you can keep me satisfied
just by being "under cover"
there's no one I rather want to have
inside my phone

[Chorus]

Suddenly, suddenly
This is pure ecstasy
suddenly you appear with the key to my heart
Suddenly, suddenly
I will never be lonely
you are my only
The key to my heart [2x]

You're all that I ever
and it's now or never
You're forever the only one...

[Chorus]
