When the dispiriting present is too much with you, set your Packard's radio dial to Star 790, KBME. That's AM, of course. KBME ("BME" stands for best music ever) exists in a time warp before FM ruled the airwaves, in the American past somewhere between the Great War and the Beatles. Here Eydie Gorme still blames it on the bossa nova, Russ Morgan dances with a dolly with a hole in her stocking, and Ella Fitzgerald cries over you. Between songs, the folksy DJs discuss the personal lives of celebrities who passed on years ago, then pitch financial-planning services and organ lessons to the Greatest Generation. "That old black magic has me in its spell," sings Frank Sinatra, and you think he's lucky: Old magic is often the most powerful kind.
