Thanks to the proliferation of Broadway tours, South Florida audiences are never far from at least a glimmer of the Great White Way. What's harder to sample are the off-Broadway hits, shows whose quirkiness or bold attitudes preclude them from fitting into the mainstream. One such musical was Das Barbecü, the riotous, Hee-Haw-inspired adaptation of Wagner's Ring cycle presented by the Actors' Playhouse. How do you stage a spoof of a three-day opera marathon in two and a half hours? Apparently by throwing together Giants, Norns, Rivermaidens, star-crossed lovers, and the rest of the gang of Teutonic trillers (all possessed of Broadway voices) with sequins, lassos, and kitschy lyrics. "I could eat a/Pound of Velveeta" is one of the memorable lines we can't get out of our head. Nor do we ever want to.
