(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
