You say you don't feel it is meant to be a tribute to things of the past. I point out evidence to the contrary. Yes, not everything is explicitly cowboys or a time period. A lot of it is wilderness based, which is a part of being frontier themed. I point out a direct quotes through analysis to provide evidence where the main character says it is a show they are putting on for past and heritage. A frontier revue through an anthropomorphic bears point of view. Like the tiki room with their silly impersonations of at the time, easily recognized popular culture icons, it is meta. That does not change the fact that it is a tongue and cheek frontier revue parody. You can critique the execution, but the evidence is there of the show's intent, both through dialogue and the main character wanting to sing about Davy Crocket with a living Raccoon skin cap and songs sung through a bears point of view which makes songs like Old Slew Foot different levels of wordplay funny.
Its Meta the same way Wally Boag's traveling salesman character was played in The Golden Horseshoe as a variety show. He can interact with the audience with modern sensibilities and jokes, but it was a love letter to a different time and place.
