I hear that train a comin'
Learned in on my guitar years ago.
The Memphis boys. I followed both their careers from the beginning and both came from Sam Phillips great stable of talent at Sun Records. Saw Cash in person in his heyday, he was great but have to go with the big E for what he did for Rock 'n' Roll.
I know Elvis was more popular and had far more influence.....but I prefer Johnny Cash by far.
Rockabilly beats country by about a million to one. Even if it (and he) aren't among my favorites. Liked Cash's voice better though, especially in his later years.
The Man in Black.
