Back around 1992, my brother hired Mark to entertain the children at my young nephew's birthday party in Los Angeles. After the festivities were done, and the children were gone, Mark sat down with about five adults and told a story that he never again (to my knowledge) told in public. It was called Knight of the Blitz, and once in while at storytellings I'd attend I would call out for him to do it... but he never did. It was as marvelous as any of the tales you and I know and love, that he repeated so often, and it breaks my heart both that Mark is now gone, and that this tale may well be lost.
