I agree that the plot slows things down, but it is not that long. Once they get into the acts this is first-rate fun, sort-of a quickie flickie Ed Sullivan type thing. Almost all of the acts are worth watching. I especially liked it because of Spade Cooley, the western swing leader on the west coast where he outdrew Bob Wills who had things sewed up in the midwest and South.
In real life, Cooley was no angel - shot his wife in front of their 10-year-old daughter. While in prison he went out now and then to entertain, I guess, some lawmen, keeling over during a sheriff's get together. He was not easy to work with so the stories go, but the end product was outstanding. By the way, and you will notice the resemblance, he served as a stand in for Roy Rogers a couple of times.
The Ginny Jackson in the screenplay was his wife and Cooley himself was a producer-writer of this little fun piece.
Hordes of familiar faces appeared through the flick, but the main thing were the artists, acrobats, etc., including some boogie Latin by Chuy Reyes, and an appearance by the Sons of the Pioneers minus Rogers and Bob Nolan, but with two other western notables, the wonderful Ken Curtis and Shug Fisher.
If you don't want to tax your gray matter, if you just want to have some fun, grab "Everybody's Dancin'," which, by the way, is part of an eight-package deal of similar offerings by VCI. Yay for them. One more thing, the accompanying short subjects are fun, although one of them didn't show up. Can't have everything, but this short movie does.
