On the 30th anniversary of the King's death on his throne, Lisa Marie broke down and did the Nat-&-Natalie/father-daughter corpse duet thing . . . for charity, of course. It is, of course, a train wreck: Elvis onstage in the '70s, babies playing with handguns, Lisa Marie decked out in zombie eye makeup, her face transformed with faux-religious solemnity as a tear drips slowly down her face. In short, it's tacky, morbid, garish, and gorgeous -- all of the qualities for which we love the Presley clan and its ruins at Graceland. Debuted last night at the end of a particularly intense Death Week (the annual Elvis confab in Memphis), it's available on iTunes as a single.
