Billy Hill & the Hillbillies are actually 4 brothers all all named Billy Hill who grew up in the hills of... (wait for it)... Santa Monica.
They are a Bluegrass band, with some rock n' roll and a lot of comedy thrown in. Actually, there are 3 teams--gold, blue and green. I like the gold and blue teams the best because they both have the hilarious Kirk Wall and the extraordinarily talented Dennis Fletchet. They play inside the Golden Horseshoe five times a day for about 30-35 minutes. Most of the humor is something kids that age should get, so if your kids like music, then yep, take them in. I don't remember the entire schedule (there are a few fan sites with it up--you can put Billy Hill and the Hillbillies into google and they'll come up) but green is on Fridays, gold is on Saturdays and blue plays on Sundays. The blue team has a cd that they sell in the Bonanza Outfitters and in the music shop on Main Street.
