Comparing two List that a "Close" but not Identical

[carl]

I have two customer lists. Each lists may contain the same customer but
spelled differently. I am trying to identify the customers that appear on
both list. My 2 list look something like this:

List1

Banc Two
Bear Wagner
Bear, Stearns
Calyon Financial

List2

Bank Two
Bear, Wagner
Bear Stearns

The customers that appear on both lists (using list 1 names) are:

Banc Two
Bear Wagner
Bear, Stearns

Is it possible to create the list of customers that appear on both list 1
and list 2 ?

Thank you in advance.
