A local New Orleans TV station did a video news piece on the Saturday morning Savoy Music Center jam.  It’s just over three minutes; when I viewed it, there were numerous stops and starts.  They talk to Marc Savoy, emphasize the international draw of the event, and mention its origins in 1966, with some boudin (that wonderful Cajun sausage: pork or seafood) on the counter.  There’s even a transcript of the audio.  Enjoy yourself!
