topic index for the show?

[dubhousing]

I realize this is probably too nerdy for words, but is there an index of what has been discussed on the best show and when?

I'm working on an also nerdy project for my GF, who is a prairie home companion fan, to create an old-time soundmachine (the kind with a bunch of different buttons, any of which when pressed produce a different kind of 'alien' or 'light weaponry' sound) with tom's garrison keillor impressions.  But I'm not sure how to figure out which episodes the topic has come up in.
