Please ID this "number one" song

[spiralshaman]

The song is from some time around 1987 or 1988 and the singer is a female.
The lyrics go something like this:

Number one is the loneliest number
without you I'm sure there is no other
from the first time we were both together
I knew it was meant to last forever

I love this song, bought when it came out 1987.
