I don’t know where they came up with the nickname in the story - I’ve never heard of it. As you point out, he was “Randy Andy” back when he was dating soft core porn star Koo Stark before he ‘settled down’ and got married.
She be goan’. So what difference at this point does it make?
“Soft core porn” then was just a movie with nudity in it.
Koo Stark would have been a better match. She have never gave an interview or tried to profit off her time when they were dating.
Also they call her a soft core pern, when all she did was nudity in what we call a Cinemax movie back in the day.
