Thanks for a very clear explanation of the problem. (Thanks also to 
Claus for his suggestions in a separate message.)

I guess since I use the Author/Date style of referencing, natbib 
automatically inserts the author, so this exact solution won't work 
unless  I use \citeyear instead of \cite and hard code the author 
name.  But this modification will achieve the desired effect.

I'm not sure I understand this solution entirely, since my 
bibliographies are always automatically produced by BiBTeX and an 
appropriate .bst file that I created using custombib.  Can custom bib 
create such a style, or would I have to hack my own .bst file (not 
for the faint of heart or short of time...)
