[Groop]OT Question for Mark

[Gary Grossmann]

Hi Mark!

A number of your articles about voice actors indicate they are usually a
pretty tight knit bunch.  So it surprised me to learn there were actually
quite a few other voices in the Warner Brothers cartoons besides Mel Blanc,
but I can't remember ever seeing anyone's name in the credits other than Mr.
Blanc.  Do you know why?  I would think he would want his fellow voice
actors to be listed.  (Probably he had no say in it?)  Thanks -Gary G.
