I really enjoyed reading your memoirs. I am an avid Star Wars fan, as well as an artist, and every once in a while I look for good articles to read on some of the things that interest me. All I had to do was type in Darth Vader and there you where. Keep up the good work, and maybe even check out some of my Star Wars art that I have published on my art profile sometime. satta Matka
