Her full name is Andrea Delfino. Beforehand, cheeseman had already gotten information that her initials were A.D., and from there deduced that her first name was probably Andrea, since there were several Italo disco songs that featured her vocals under the Andrea title. She has a page on Discogs, which specifically refers to her as an Italo/Eurobeat vocalist. Based on the evidence, I think we have pretty solid confirmation that this woman is indeed that classic singer from Saifam, Hi-NRG Attack, and Dima's labels who's been a mystery for a long time. I'm not sure if other people here already knew this, but since there wasn't a post or thread on this site verifying Andrea's full name, I figured I'd write it myself!
Here's a picture, for reference:

I'm not 100% if this is really her or just a model, but the woman here shows up on a handful of single covers associated with Andrea from the early '90s, so I think it's probably likely this is indeed what she looks like.
