Second item (the podcast) is a decent recording , however not 1981 more like 1991 WHY ? Kokomo is in the set - Matt Jardine , Mike K on Drums , Richie Cannata on Sax etc....
O ok, I searched "the Beach Boys 1981" trying to look for something else (the cheerleading competition where Dennis says he's from Venice) and I found that. I found actual concert footage from 1981 earlier but now I don't remember the site I found it on, I was gonna post that.
