I second this idea, but only if there's a possibility of a new Trainwreck show. Discussing the old shows is fine, but I think it'd be more interesting to discuss a new Trainwreck show. I've listened to all the old Trainwreck shows over the years at least twice, some three times or more. I truly enjoyed them about as much as a Howard Stern broadcast.
I guess what I'm saying is, it'd be cool to discuss the old shows but what I'd really like to do is participate in discussing ideas for a new show. Or, at least, the old show's newer format..or ..err..whatever.
Either way, I've been crossing my fingers for awhile at the prospect of a new show. When you guys picked up the reverse speech guy (Oates?), or Jamie Kelso, I was like.."wow, now these are interesting guests". I thought the questions you asked them were pretty much exactly what I would have asked as well. I was also very pleased at the way you treated Kelso. Most advertising-funded radio programs would have just made fun of him for an hour, then acted like everything was cool and ask him to come back next month or something. I must say, that was the most unbiased interview I've ever heard on him, and I think Art would have treated him the same way.
Anyways, there's my two cents.
