   From the NEW YORK HERALD TRIBUNE, 6 January 1948, pg. 20, col. 5:

_Robert Leonard_
_Dies, 59: Noted_
_As Comedian_
(...)  He played in "Cheap at Half the Price," of which he was also the author...
   Mr. Leonard had appeared in many shows in New York.  He played in..."Kosher Kitty Kelly"...

(Why don't "Cheap at Half the Price" and "Kosher Kitty Kelly" show up on OCLC WorldCat?  Where are they?  What are the dates?...Did Kosher Kitty Kelly eat a bagel?--ed.)
