Thanks folks!  Heres the code I have:

(define-key minibuffer-local-map "%" 'percentsub)
(defun percentsub ()
  (insert (file-name-nondirectory
            (window-buffer (minibuffer-selected-window))))))

Prior to Lennarts suggestion I had hacked together
(cadr (buffer-list))
in place of the last line which was of course quite unacceptable

Any further suggested improvements?  I guess this is going to fail in
some cases when theres no filename...

As it should, no?  You can get a more informative error with

        (insert (or (file-name-nondirectory ...)
                    (error "Selected buffer is not visiting a file")))

or you can get a default value inserted (here ".") with

        (insert (or (file-name-nondirectory ...)
