Linda Ronstadt Singing "The Only Mama That'll Walk The Line"

Here is Linda barefoot and singing a rockabilly tune on The Johnny Cash Show in 1969! I love it! 

"I'm going to hit you on the head with a pan of cornbread!" The studio audience seemed to love her too!

There is a certain charming raunchiness in her performance here that she didn't have later -- with her being shoeless and possibly missing other articles of clothing as well -- the stories are legendary.
