And it's made all the more disappointing because there is bootleg footage of her entire performance, and she is indeed tremendous in the role. I even broke a rule and posted one particular song she does, "You Can't Get a Man With a Gun," because it SO great, and because there were no alternatives to see it, and that it was a part of theater history.
The problem with that bootleg footage, besides being bootleg, is that the quality is awful. Well, I just came across an eight-minute medley of Reba McEntire in the production, and it appears to have been filmed professionally by the show itself, and is excellent quality.
It's not enough -- not nearly. But it beats having nothing, and so, here (starring opposite John Schneider) it is.
By the way, being a medley, this only includes short excerpts from the songs. If you want to see her perform the full version of that aforementioned, "You Can't Get a Man with a Gun," which she signs the bejeepers out of, you can watch it here. (The full clip is excellent, with several songs, but for those who want to see this particular song only, it begins at the 5:50 mark.)
