Mary Martin Died

Well music executives may be important in promoting (and more notoriously exploiting) recording artists but as music fans we don't remember them, whereas the performer Mary Martin will live on via her recordings forever.

And the other Mary Martin did indeed bring J.R. Ewing into the world 

No one is denigrating this particular individual.  We are having fun with the fact that she shared a name with a well loved artist and using that to make a point about where we, as music fans , prioritize Artists vs. Record Company executives.

  This Mary Martin does seem to have promoted important artists and therefore benefited music lovers.  She must have also been an interesting person to have succeeded as a woman in a male dominated industry
