(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
