Natbib citation style change?

Hi All,

I have looked in the Natbib documentation and could not find a solution to
my problem. I do not have a direct connection to the Internet and was unable
to do more research. I apologise if this is already listed in the archives /
wiki / etc.

I am using the \citet* command (native LyX) to generate a full list of
authors.

I get the following output in my document:
Yao, Smith, and Johnson.

Is it possible to remove the comma before the 'and', i.e. the output should
be
Yao, Smith and Johnson.

Many thanks

Rudi van der Linde
