I don't think Cire was implying anything quite that scale.
I assume just a group of friends like you guys had. That's not so hard. I had like five people over to my place in NYC for her Birthday in 2005. For something a bit bigger, the easiest thing to do is probably just rent a movie theater for a day. That's easy around here, and assuming a few people chip in, not that expensive (it's done for birthday parties, etc.). Might even be able to get one for free or fairly cheap if my college contacts are still good: I co-directed our
campus film festival last year, with screenings on the largest movie screen in Maryland.
Of course the best thing is still fanmeetings in Paris. Hopefully the next thing we'll be organizing is a trip to see Alizée en concert!
