It is confusing as I was thinking I gave it enough arguments, but it
requires `interactive' so I copied it from original function.

Now it is solved intermittently:

(defun rcd-async-shell-command (&rest args)
  "Remembers last async shell command on `C-c l'"
  (interactive
   (list
    (read-shell-command (if shell-command-prompt-show-cwd
                            (format-message "Async shell command in `%s': "
                                            (abbreviate-file-name
                                             default-directory))
                          "Async shell command: ")
                        nil nil
			(let ((filename
			       (cond
				(buffer-file-name)
				((eq major-mode 'dired-mode)
				 (dired-get-filename nil t)))))
			  (and filename (file-relative-name filename))))
    current-prefix-arg
    shell-command-default-error-buffer))
  (let* ((shell-command-buffer-name-async (concat "RCD Async: " (format-time-string "%Y%m%d%H%M%S")))
	 (last-buffer shell-command-buffer-name-async))
    (global-set-key (kbd "C-c l") `(lambda () 
				     (interactive)
				     (switch-to-buffer ,last-buffer)))
    (apply #'async-shell-command args)))

Now I can bind it:

(global-set-key (kbd "M-&") 'rcd-async-shell-command) 

And now it works, when I wish to get the last async buffer I just
press `C-c l'.

Because buffers are named by year and time: 
(concat "RCD Async: " (format-time-string "%Y%m%d%H%M%S")

I can then make a function to browse backwards in time those async
buffers.
