Think about how many music groups you've seen come and go in your lifetime.

Very few can say they've been around for half a century, let alone 75 years. But that is the case for some cowboy crooners who now call Branson home. We stopped by to see how the Sons of The Pioneers are celebrating a very big birthday for this Oliver's Ozarks report.

Since 1934 The Sons of the Pioneers have sang about the cowboy way of life in the old west. 75 years later they're still on stage in Missouri's music city.

"It's been a good journey. Well it started back in the early 30's with Bob Nolan, Leonard Sly, and Ken Spencer" says Luther Nallie, band member.

You know Leonard Sly by his stage name, Roy Rogers. The 'Sons' started on the radio, and their simplistic songs about tumbling tumbleweeds and cool water earned them a loyal fan following that continues today.

"The Sons of the Pioneers in my opinion, have a unique harmony that nobody else does" says Pat Collins, Arkansas.

"I think it just appeals to everyone. Great harmony, happy. Happy music" says Ginger Holland, Texas.

The six men who make up the group today perform at Shepherd of the Hills in Branson. Folks who show up to listen to the tunes are transported back in time, to the days when cowboys roamed the range and got their meals straight off an old fashioned chuck wagon. Those who keep the coals hot and ring the dinner bell, enjoy the experience.

"A cowboy transcends all language barriers. You go to foreign country, they know cowboy. And so i know that I'm passing that on" says Travis Loewen, trail cook.

With only 33 members in the group's history the music today sounds much like it did 75 years ago. All these years later fans are still memorized by the melodies.

"it's kind of a sentimental thing. People remember seeing the group when they were kids" says Nallie.

"Cowboy music either paints a picture or tells a story of the west" says Gary Lemaster, band member.

"We'll play songs of the movie cowboys. We're not real cowboys" says Nallile.

But the 'Sons' are a real treasure, as proclaimed by the Smithsonian back in the 1970's. Their style is so unique that many have tried to copy it. And these guys understand why.

"You can play one note and it's nice, two notes and it's nice. But you put four together, and it's so beautiful when you do it with voices" says Lemaster.

So with 3000 songs in their repertoire and 75 years experience under their belts, The Sons of the Pioneers no doubt have a loyal following. It's why they hope to keep crooning about cowboy culture.

"And that's what the pioneers are noted for. They began cowboy music" says Loewen.

The 'Sons' got their name because Roy Rogers and the first members went on the radio very early on. They were called the pioneer trio. But the announcer believed they were too young to be pioneers, so he called them the Sons of the Pioneers, and the name stuck.
