Please?!!help ..if you can. Trying to cancel an event w/a celebrity.

[lildreamer316]

Let's say a dj and his partner were given one night a week at a nightclub to run with, and see if they could make money at. So they did two test nights running a certain kind of music show (house/trance/electro/dubstep). They were told that if they made a good showing after three or four nights they could have the whole club to run in a month or so.
So they start calling around to see if they can book a semi-celebrity in the club, to get a good showing. They get this guy who says he can book this certain celebrity dj (not a HUGE celebrity, but on tv and such..maybe B or C list; has name recognition). This guy, let's call him Bo,(-one of our friends has known him for several years, btw; he is known around town and *says* he is friends with a BIG name in hiphop) hems and haws a bit, but finally comes through with a contract. So the aforementioned friend of the dj reads it, signs, and pays the retainer(at my house, btw..I saw it happen).
This guy Bo has been kinda lax on getting the flyers and promo info to our friends,but he does finally, five days before the event. Our friends have also paid the radio stations in the area to run spots for this appearance (on their own dime).
The event is tomorrow. This evening around 5PM,our dj friends found out the semi-celebrity has posted on his facebook that this show is a fake, and he is not booked for it. BTW,this celebrity's tv show is on a major cable network.
Now someone has to go on one of the dj's facebook pages and remove the posted event. IN CASE OF BEING SUED, what kind of wording should one use in the phrasing of the apology/reason for canceling?

I am sorry to ask this here but this is time sensitive and I have no one in my phone book to answer this kind of thing. Any help would be appreciated.

Good to be reminded that the shorter the better.

2. Perhaps not use the word "canceled," since the show never existed?

Something like "Previous announcements of a DJ So-and-so show were in error. We apologize for any inconvenience."

I would think that it would be wise to make some sort of contact with the actual celebrity DJ, who apparently knows about it, as that seems to be where the lawsuit risk is. Also, legal action against this Bo swine would be advisable...

3. Thanks.

Since there was an actual contract (of some sort) I believe legal action will be forthcoming.
Thanks for the help; much appreciated.
