In case you were wondering, My Morning Jacket frontman Jim James is single. But his heart is not. And Sunday night at a sold-out, solo Valentine's Day show at the 400-capacity Rathskeller venue in his hometown of Louisville, KY, the rocker -- billed under his solo nom de tune Yim Yames -- dedicated a cover of Buddy Holly's "True Love Ways" to a mystery woman, "wherever she may be," he said. Opened in 1907 in the basement of Louisville's Seelbach Hotel, the Rathskeller is a swanky place with ornate walls and a domed, grandeur ceiling, and it's where author F. Scott Fitzgerald regularly drank. Sunday's crowd arrived in snazzy cocktail attire, lending an air of romance to the rich, vintage, and exclusive feeling of the venue.
