I managed to catch it this morning on Good Morning America.
Wasn't a very long interview from what I saw, but it was very interesting imo....one thing she talked about (that I've never heard her mention before), was her demeanor the day he passed away, of how she "rode her golf cart around and smoked cigarettes in the guard house even though she was only 9 years old ".
Lisa also talked about the "upstairs" of Graceland, and said that "she does still go up there". Diane asked her if she still slept in the house, and Lisa responded by saying "no, but I have before and that it's kinda dusty up there." They also talked about Lisa's room still having alot of the same things in her room as it was on the day Elvis died.
She also took Diane Sawyer (who conducted the interview) in to the secured building that holds many of Elvis' posessions, and they discovered a blue napkin (or cloth) that Elvis had written a message to Lisa on that shocked Lisa causing her to say "she had never seen before", causing to her to tell the attendant "I want that, I'm going to put it in a frame."
Overall, I thought it was pretty good imo....maybe someone can post a complete transcript?
