Hi Howard,
The page is in Google index because you are still linking to that page from your website. Here is the page from where that page links:

As you are linking that page Google indexing the page. Google come to know about "noindex" tag before that he has already indexed it. Sorry for bad English.
Lindsay has written awesome post about it here:

After reading above blog post, my all doubts about noindex, follow, robots.txt get clear.
Thanks Lindsay
