I am about 98 percent certain I went to college with John. If it wasn't him, there was a bloke on campus who could have been his identical twin. The dates for his porn career in the 1980s correspond to the right years for him to have been in Southern California.
Unfortunately, I didn't see him in porn until after I graduated. Even if I had, however, I was too shy at the time to go up and ask "weren't you in Glory Hole of Fame?" Smut producers regularly posted flyers on campus bulletin boards looking for male and female students to appear on camera, so the opportunity certainly was there.
