(duet with cliff richards)

Janet: i know we just met, but i feel like i've known you before
Cliff: but something about you my heart has been searching
Janet: i don't understand it, it's over my head
Cliff: so don't try to solve it, just feel it instead. ooh

Chorus:
It isn't really such a mystery
Anyway you add it up it turns out to be
Attraction automatic, a simple mathematics
Two to the power of love

Janet: i look in your eyes and everything falls into place
Cliff: you don't have to say it, it's written all over your face
Janet: by my calculation, i'm falling for you
Cliff: it's a perfect equation
Janet and cliff: and i know that it's true

Repeat chorus

Janet and cliff:
It's complicated, but it's easy to see
A combination that was meant to be
It's something you can count on

Repeat chorus

It isn't really just a shot in the dark
Somebody must've worked it out on the chart
Attraction automatic, a simple mathematics
Two to the power of love
