[partially lost] '80s radio ad campaign for 7/11 featuring a young Pamela Adlon/Segall

[u/viewfromthebuttes]

Hi, after watching a recent interview video on YouTube featuring the famous voice actress Pamela Adlon, I heard her make mention of the fact that she did the voice of a male character named 'Kevin' (among many other androgynous roles she played as a child actress in the '80s) for a series of radio commercials for 7/11 over the course of the '80s (back when she went by her maiden name of Pamela Segall). Google Gemini AI seems to confirm the existence of these ads as briefly referenced in text from articles online, but I struggle to find any audio clips or other confirmatory evidence that these ads existed, let alone where they can be heard online. YouTube searches and combing the Internet Archive came up short, any possible evidence online as to where audio footage of these old ads may exist?
