Hello Stephen, I finally have a chance to respond to your posting. Jon lives in a nursing home in North Carolina. He will be 77 in May. You are correct in observing that he is no longer on Facebook. He is doing well and I let him know that you were asking about him.
I am pleased to see that you look back on the "Annie People" years favorably. I do too. I am very proud of what Jon and I accomplished with "Annie People" over the years -- all the interviews and analysis we did, and the fun we had sharing the love of the comic strip/Broadway show/movie with fans such as you. You are correct that issue #90 of July 1999 was the last paper issue. I wish I had been able to continue the newsletter longer, or had given it a proper conclusion, but unfortunately "Real Life" got in the way and the newsletter just stopped...
However, when Julie gets the new AnnieOrphans website posted, I have given her PDF scans of all 90 issues, PLUS a bonus digital exclusive issue #91 which contains material from 1999 that was never published. I hope having 91 issues of "Annie People" hosted on Julie's website will be good resource for history for old and new fans alike.
