Jackanory was a popular British children's television program that aired from 1965 to 1996. It featured celebrities reading stories, and there are extensive records of those appearances.
It's possible that Louise Lombard was never approached to read on Jackanory, or that her appearance may have been a private or one-off event that wasn't widely documented. However, it's important to note that there is currently no publicly available information to confirm that she ever read a story on the show.
