Officials says last weekend's HullabaLOU Festival drew nearly 79,000 music fans from across North America, despite the searing summer heat. The three-day event featured 66 musical acts on five stages across the racetrack grounds.Churchill Downs Entertainment President Steve Sexton says the event will be back in 2011."We are extremely pleased and overwhelmed, candidly, by the fan response that we've gotten. Ninety-nine percent of people say they would recommend people attend the festival in 2011, and the response has just been terriffic," he said.Sexton says other than hoping for better weather, the only significant change officials are looking at is the scheduling of certain acts. He says some fans complained that some of their favorite classic rock artists peformed too close together.
