Solved: "Opposites attract..."

Any idea the female who sung this late 70s-early 80s?


"You said you'd be over after 10
I sat home & waited until then
didn't you know my heart goes bang bang when I know you're near
I confirm you have that magic touch
will you say you love me very much
don't you know things are never what they appear
I'm assured that opposites attract
when I'm sure of you I might react
didn't you know I was living under your spell
now when I consult my crystal ball
it doesn't look so wonderful at all..."
