For years I had no interest n podcasts, but I've grown to love having the ability to "dial up" something being talked about that's of interest to me -- not necessarily "live", but whenever I'm in the mood for it. It's nice to know that when I want something to listen to, there's a world of stuff out there.
Now, as to BK doing one? I'd be all for it. There's no way that wouldn't be of interest. Chatting, reminiscing, demonstrating a song, comparing this or that, whatever.
I would say the same about a few other people I know whose interests and areas of expertise are known to me, and trusted -- trusted, meaning I don't have to wonder if I'm being fed a load of BS on a given subject; I know that they know what they're talking about.
So yeah, bring it on! And no, I don't have the slightest idea how to set such a thing up.
