Kojo Nambdi had Richard Sarles on one hour of his show yesterday on WAMU. You can listen to the podcast of the interview by going to http://thekojonnamdishow.org/shows/2011-02-17/metro-general-manager-richard-sarles. Since it is the WAMU pledge drive, there is at least one long gap in the show where they fundraise but you can just skip over that (once it starts, skip ahead to about 30 minutes). I haven't listened to the entire thing yet, but so far there isn't anything too noteworthy on the broadcast.
