My brother used to perform a "card trick" for his children called
"Little Louie".  This trick involved stacking a standard card deck in
a particular order then telling an amusing story as the cards were
dealt out.  For example: He would explain that "Louie took a cab to
435 Queen Street" as he dealt out a 4,3,5 and Queen from the deck. (I
am making up this example, as I cannot remember the exact story). The
story continued until all the cards were laid out.

He has unfortunately forgotten key parts of the story, and has lost
touch with the person who taught it to him.

Have you a source for this?

I seem to remember seeing the trick performed on "World's Greatest
Magic V" (1998) if you can obtian copy of that. You won't learn the
trick but you'll see it perfomred and hear the story (there are many
variations of it apparently).
