The character is played by Jimmy Dean, who was a regular star on the last year or two of the series, and he often sings and plays guitar, which I guess he was famous for before appearing in the series. The voice I thought sounded rather familiar, and it turns out after his acting career, he made an even greater fortune in the food business with Jimmy Dean Sausages, and his voice is still used in the commercials 50 years later. Although he himself has passed away.
I bet you're more familiar with him than you know, given you're about the same age as I am.
Jimmy Dean had a huge hit record back in the day with "Big Bad John," .
In addition to music and sausages, he also had a supporting role in "Diamonds are Forever," playing the Howard Hughesque "Willard White."
