What was the former profession of Andrea True, who had a hit with the disco song "More, More, More"?

little b, yeah that doesn't surprise me

Aziraphale , More, more, more! How do you like it? How do you like it?

never heard of her or the song

I vaguely recalled her name, though I don't think I saw any of her films. I had no idea she sang that iconic disco era hit.

never heard her name before now

Aziraphale , Any time disco is played, you'll hear it. At least in the US, don't know about other countries.
