Casting a band is not as new as it seems. What is new, is that it does happen in front of a TV audience. Darby and Tarlton were not friends but business associates put together by music managers who thought that it might work. And, what a surprise, it did!
Apart from the fact that Jimmy Tarlton introduced the slide guitar to country music, they also wrote and recorded two of the biggest country hits of the 20ies: "Birmingham Jail" and the "Columbus Stockade Blues". But it was the success of the songs that carried the doom of downfall for the duo. They were openly hostile to each other right from the beginning on one hand, but produced a magical sound that still sounds rich with imagination almost 80 years later. But as it was they couldn't agree who was the father of their hits, and who therefore should make the most profit.Their last recordings as a duo were made in 1933, 4 years after their last big hits, but the magic was gone by now.
In the course of the Folk Song Revival they were reunited giving a glimpse of their lost talents, but being as hostile as ever.
