NOTE:   This program hadt a phone line glitch took place early in the program.  I used a backup copy of the recording to replace a lost 13 minutes or so early in the show.  The backup audio is not as good as original audio but nothing was lost in the interview. When the program was restored, Roman quickly summarized the 13 minutes in case the back up recording missed it. Thus, you have the original part of the interview plus a few minutes of Ruman's summarizing what was missed as a result of the phone system going offline.  The written summary for this program will post later this day.
