(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
