I saw him last year and now he's on the "must see" list for future trips! It's a very interactive show, and only the sourest of sourpusses don't get involved in the singalongs and other antics. Amazing energy level, very funny--he's like a cartoon come to life--and the man is just plain talented. Get there early if you want a seat in the main lounge; it's well worth the time and the wait for the show is a pleasant one thanks to the great cast members at the River Roost.
It's also a kid-friendly show; kids were having almost as much fun as the adults.
My dh and I loved the show. We went last august amd are returning this August with family and have told them its a must do. Its so much fun and great for every age.
