(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
