I read that article.
It lacks corroboration from the casino that they either paid the band sufficiently to make trip worthwhile, or that such a large number of musicians did, in fact, play.
This casino has a 450 seat theatre. My very small town's high school has a larger theatre. It books acts like The Mariachi Divas who no doubt arrive by Tijuana Taxi.
The Homelame Security story is the one that is full of holes.
