So for years I have been trying to identify what this was used for. I found out today! Turns out in 1989 Disneyland had an "All-Star Gala" event for the MLB All-Star game, which was being held at the Angel Stadium. The event was repeated at Disneyland in 1990, but the game was held at Wrigley Field in Chicago. So in case any one ever asks you what the Cowboy Boot n' Ears Revue was, now you can tell them.
