Can lightning strike twice -- posthumously? Well, Natalie Cole and the late Nat King Cole have another lucky strike with "Walkin' My Baby Back Home." Following their 1991 Grammy-sweeping "Unforgettable" ballad, they're back on a more lighthearted duet. Dad sounds dandy, as always, and daughter, with her thinner voice, pales a bit by comparison but holds her own on this finger-snapping delight. She handles the vocal chores on the rest of her new CD, "Still Unforgettable" (out Tuesday), doing tunes from the Great American Songbook not necessarily associated with her father. Don't miss the delicious "Coffee Time," a 1945 Fred Astaire number Tony Bennett introduced her to just last year.
