I just rediscovered this show on youtube and was wondering the same thing. Might be some of my favorite youtube clips of Brian and Co.
Does anyone have the full show? Clearly it was recorded *somewhere* though I suspect maybe only a portion (which has found its way to youtube) was actually broadcast. I love all of the official BW released
Here is one of 6 (which you can find in the Up Next column).
