Dear Group:
Though I have read several biographies, I do not remember if the question I 
am asking was ever answered.  Did anyone actually call Twain "mark" when 
they greeted him?  My assumption is that Mark Twain was his name only in 
writing or in introducing him.  I also assume,  perhaps incorrectly, that he 
was rarely addressed as Mark".
I was just wondering.
