Question: Bruce Henning is hired as the booking agent for a rock group, the Understanding Slugs. He negotiates and signs a contract for the group to appear in one evening performance at the Wisconsin State Fair in Milwaukee.
Two months before the show date, Henning informs the Milwaukee producer that the group cannot appear as scheduled because "they'll be tied up in a two-week appearance in Vegas-a big break we just can't walk away from." Are the Understanding Slugs liable to the Milwaukee producer for damages for breach of the earlier contract?
