Olympics on the Moon

Now that Rio de Janeiro has been awarded the 2016 games, who is going to bid for the 2020 games? One suggestion is the moon. The Internet Search Challenge is to find the date of the earliest online reference to a moon Olympics. Let's start with March 30, 2007. I know you can beat that.

Post your answers and references in the comments.

P.S. I don't know the earliest answer (just that there's one earlier than March 30, 2007). You can help find the earliest and turn this into a student challenge.
