I've caught bits and pieces of interviews on YouTube. What I've heard he seems to have mellowed with age, was just never a fan (plus I was working a lot when his shows aired)
I did recently catch an interview with one of his former program directors (not Pig Vomit, but the guy who replaced him) and he said he got along great with him at WNBC.
Back to the original premise of the Biden interview, I hope to catch it on line. It would probably be better than most mainstream interview with politicians.
