Garrison Keillor made his Grand Ole Opry debut over the weekend, with help from country music greats Chet Atkins and Roy Acuff. Keillor, who appeared Saturday on Acuff’s segment of the 63-year-old show, was accompanied by Atkins on guitar. He sang “Cat, You Better Come on Home” and “Sweet Hour Prayer.” “There’s a tradition of dog songs in country music, such as ‘Old Shep’ and ‘Old Blue,’ ” Keillor said, “but I’ll bet this is the first time a song about a cat has been sung on the Opry.”
