New Post: Modifying IEEE to remove 'and' - Elsevier style

Hi, I'm attempting to modify the IEEE style to match a journal published by Elsevier. The biggest difference I can tell is the use of 'and' between the last two items in a list of authors in the bibliography. I've attempted to remove the ", and " and replace it just with ", " however, I now get a comma after every entry including if it is a single author. Any suggestions?

Thanks
Sham
