There are so many wonderful sites, blogs and Facebook pages about George Michael, far too many to mention here. But here are a few I like myself.
George Michael NL
Arguably one of the very best GM sites out there. Remember to visit the astonishingly beautiful section on The Symphonica Tour and the 25Live Tour.
A lovely Facebook page - posting photos, articles and more.
George Michael News
A French blog with a huge wealth of articles, videos and more. This link goes to the English translation of the site.
Facebook Group: George Michael
One of the many, many Facebook groups around. Friendly atmosphere and strictly moderated, so no spam or nasty comments.
