Everybody, it seems, has a favorite story about barbecue. Here's mine. Mrs. Duggins and I took a road trip to Memphis. We were going to see Bonnie Raitt in concert. Now, when it comes to barbecue, Memphis has Elwood’s Shack, Corky’s, Fat Larry's and they all have their fans. But with apologies to all, this story is about Charlie Vergos Rendezvous. And, Robert Moss has me beat. He's author of the book "Barbecue, The History of an American institution." It's in a new and expanded edition from University of Alabama press. He joins me next on APR notebook.
