The Porter Wagoner Show.
Anyone actually remember his TV show? If you have RFD-TV they air reruns of it which is kind of interesting, along with a few others which is kind of interesting since these type of shows aren't usually seen in reruns. Wonder if these RFD showings of it are the first time it's been aired since its original broadcast? Also notice how the network often edited out the closing credits?
I've read that's while Porters show was nationally syndicated, it was more popular in the South and maybe not as big elsewhere.
Notice how in the 60's shows the beginning of each episode they show him walking down the hall through the door into the studio.
