One of the early proponents of talking blues was a fellow named Robert Lunn. Robert was a regular on the Grand Ol Opry in the late '30's and early '40's. At one point he received more fan mail than any other Opry performer. Starday Records issued an LP a number of years ago, but I don't know how a person could get a copy unless some 'Catter has it and would make it available by copying it. Songster Bob mentioned in a post above that The Original "TALKING BLUES" from back in the late "20's and gave a brief quote of some of the lyrics. Robert did a "cover" of that particular song. An additional part went something like:
Down in the henhouse on my knees
I thought I heard a chicken sneeze.
It was nothin' but the rooster sayin' his prayers,
Givin' out orders to the hens upstairs.
Just a preachin';
Prayin', too;
Givin' out religion.
