Please provide transcripts or broadcast dates. I listen to Rush quite a bit and don't recall his saying he "had a phone call from someone who went to college with.....etc."
I think it was on a Thursday, early in the program, but I'm not going to do your work for you. He's probably cleaned it up a bit by now.
I should think that had he really said this, there would indeed be a "clamor" for his source.
No "clamor" for the reasons I gave.
Since when did you start listening to him more than two minutes a month?
