Only the locals show up in the winter. They come with guitars and bass fiddles and old songbooks, and they gather in the studio to do a radio show that you can still hear in some cities, but not in so many as you could a few years back. The show starts around 7 and winds up at 9:30 -- just about the time the hillbilly singers and the Bluegrass banjo champs are warming up at Gerde's in New York's Greenwich Village.

Folks around here don't have much time for strangers. You ask what goes on at Renfro Valley and they shrug and say, “Not much.” You want to find a restaurant after 8 p.m. and -- if you can find anybody to ask -- they'll direct you to Lexington, an hour's drive.

You have a thirst and they tell you, “This here's a dry county.” Pause. “Yep, dry county.” Another pause. “Maybe if you go up the road a piece to where you find a sort of restaurant, maybe somebody there can fix you up.”

So if you want entertainment in these parts, you go to Renfro Valley and you go early. The studio is warm and the music is every bit as real as the people who sing it.

“Well, now, for all you folks out there in radioland, I want to say that we got a little gal visitin' with us this evenin'. Little Brenda Wallen, from up in Winchester, I believe. . .”

And little Brenda sings: “Beeyooteeful lies, beeyooteeful lies. . . each one a heartbreak. . . in perfect disguise. . .”

Then the Hibbard Brothers quartet, lean mountain faces and huge hands poking out of gabardine sleeves -- “O, what a time we will have up in heaven. . .”

A murmur of approval from the audience. A flashbulb pops near the back of the room. Things are picking up. The Farmer Sisters take their turn at the mike, with a rippling version of “You're the Reason.”

A few cheers from the crowd, a quick burst of fiddle music from a man beside the piano, then somebody holds up a hand for silence. Time for the commercial.

“This here's a long one,” says the announcer, glancing at a yellow script in his hand, “so let's do it all at once and get it over with.” Snickers from the audience. Everybody grins as the commercial is read very earnestly into the mike that will carry it out to the Good Lord only knows where.

The announcer finishes and heaves a sigh of relief, also into the mike. Everybody laughs and the show goes on. Meanwhile, the Greenbriar Boys are tuning their instruments at Gerde's; in a few hours there will be a long, button down line outside the hungry i in San Francisco, waiting to hear the latest hillbilly sensation.
