I wouldn't mind the update, but ONLY as long as they involved a producer who understands country music history as much as the original writers did. The songs they chose were not only tongue-in-cheek appropriate for a bear attraction (especially "Old Slough-Foot," a.k.a. "Bear Tracks," and the Davy Crocket song), but they were also classics that can stand on their own.
They should not try to be trendy.
This CAN be done, by the way. They should hire whoever put together the "O Mickey Where Art Thou" album for Disney in the early 2000s. That album featured the best Nashville had to offer, not only in the headliners but in the studio musicians and backup singers. Charlie Louvin would not be well known today, but was an architect of country music and his voice fit perfectly in that project for the song he was chosen to sing: "I Will Go Sailing No More," from Dumbo, for which his voice as an elderly man at that time in his life gave that song an amazing poignancy. Other songs were done amazingly well, including Collin Raye and the Jordanaires giving "Circle of Life" a touch of the country anthem "Will the Circle Be Unbroken" in the instrumentation, which melded the current with the past... perfectly representing the "Circle" it represented.
My point is that if they update the show, it can be done well as long as they include some folks who love the genre and have depth within it, as they did with that album (which could easily have been done with less care, but I am glad it was done with care). But if they don't want to go that effort, then leave it alone.
