Really good early Autry, an expert mix of story, music and action. I also learned what a difference electricity made to rural communities. We tend to take electric power for granted, but the movie is set in 1938, soon after Boulder Dam was built, and the bad guy is using the promise of electrification to scam Depression era folks. It's really worked well into the plot, better than any A-movie I've seen, and even produces a good laugh.
Anyhow, Gene gets to do some hard riding in order to thwart their plans, along with an action-filled mine tunnel finale. Frog has a fairly straight role minus the usual clownish humor. What a fine versatile performer he was. There's also a did-I-really-see-that novelty act that beats out tunes on about everything but rocks. Include too a lovely Carol Hughes as eye-relief from all the ugly guys, and you've got a near perfect package of Autry entertainment.
