Miss the marker out front, and you might confuse the building for just another office on Nashville's Music Row, but step inside the Mike Curb College of Entertainment and Music Business, and you'll find the studio that gave us many of country music's most historic recordings.

Don Cusic is a Professor of Music Business at Belmont University. Counting the floor tiles between the control room and the studio's sweet spot,  he explains it was here that Roger Miller recorded King of the Road, Johnny Cash cut Ring of Fire, and Patsy Cline polished all of her hits with producer Owen Bradley.

"You know a great song lasts forever. And a great voice lasts forever," Cusic told us in an interview. "And if you get a great voice singing a great song, it lasts forever."

Today, Music City is a major commercial center, but the clubs on Broadway still serve up plenty of cold beer, country music and echoes of another era.

Charlie Dick and Patsy Cline married in 1957, and they moved from Winchester to Nashville two years later when Dick was discharged from the Army. Cline already had a hit.  Walkin' After Midnight took off after she  appeared on the CBS Television Program, Arthur Godfrey's Talent Scouts, but it wasn't an easy ride.
   
"You did a tour. You'd leave and might not be home for a month and work 20 days out of 30 or something like that," he said. It  was only in the final years of Cline's life that she achieved financial success.

Gold records line the walls of a room in Dick's suburban Nashville home, but 50 years after her death in a plane crash, and countless movies, musicals, books and documentaries, there is something else that Dick wants people to know about Patsy Cline.

"She had a good heart," he said. "She helped a lot of people, Loretta and Dottie and people like that, and she was a good momma," he said.
   
For fans like Linda Carter, Patsy Cline's music holds an enduring appeal.

"I Fall to Pieces is my favorite," she told us, "and Sweet Dreams of course, Crazy, I could just go on and on. Walkin' after Midnight," she laughed.

And many have been streaming through a Nashville exhibit at the Country Music Hall of Fame and Museum. Open through June 9th,  it includes examples of Cline's costumes, letters and personal items, including a whimsical collection of salt and pepper shakers.

Mick Buck is the Curatorial Director. "I think it's remarkable that she really only recorded for eight years," he said. "Of course, she passed away when she was only 30, and yet here we are 50 years later, and her legacy is perhaps more powerful and important now than it ever was."
