I love the straight dope podcasts. My favorite part is the intro/outtro music. Who is the artist of this? I’d like to hear more!
I don’t know, but it sounds like music used in game shows from the '60s.

I know this is about the podcast, not the boards, but I’ve moved it over to ATMB anyway. I don’t know the answer myself, but one of the other staffers probably does.

A visit to the website of the sponsor, Ska Brewing, reveals more of this music from “The Toasters.”
There’s a music player on the site so you can listen to more.

The tune you hear on the podcast is “Don’t Let the Bastards Grind You Down.”
