If you're listening to Randi somewhere, you'll notice there is now a repeat of the show from a day or two ago. That's because about 20 minutes ago her control booth in L.A. brought up a conversation involving a bomb threat - and did so in the middle of a commercial, which was extremely unusual.
The back-and-forth between Randi and the engineers stated that there was a bomb threat received in the Los Angeles building and that they were putting on a best-of set for the rest of the afternoon, which they did.
I never listened to a show that interrupted itself like it did, but on a day with a lot of other stuff breaking, add this to the fire.
Hopefully others will be able to contribute what they hear about this as news develops ...
