An opening-day attraction, one of the last to survive, the Jamboree is a 10-minute vaudeville-style revue that, at one moment, has 18 Audio-Animatronic bears, a raccoon, and a buffalo head singing country music together. Some kids, particularly pre-Ks, are enthralled by the dopey-looking robots, which appear for a verse or two of a saloon song, and then are retracted away. Other kids, and many adults, are powerfully bored. It’s nice to sit, but don’t wait more than 20 minutes for it unless you’re hankerin’ to see a vintage Disney museum piece.
