Do you know who asked for it to be removed from youtube? Much of G4TV's programming is available (at least partly) on their website. There's a good chance programs like this might return this year with the official release as people dust off and relook at their old SW media. Might want to add usenet to your list of places where this might show up.
Would love to also see the G4TV 'Star Wars in Japan Celebration' special.
