Update a few minutes later:  Alright, I split up the footnote into three separate ones.  There is no card catalog number for the 16 millimeter film of the First Tuesday NBC television segment.  Just go to the film library and ask for Janis Joplin: Portrait of a Ripoff.  It was broadcast shortly after the January 1971 release of Joplin's posthumous Pearl album, which got a lot of publicity because she was recently dead at the time.  If this is not good enough, I give up.  You won't hear from me again.  Other stuff I put in this very popular article was deleted by Wikipedia regulars  are they considered vandals ?  I don't care anymore.    dooyar
