A video of Elvis Presley duetting with his daughter Lisa Marie will be posted on the internet to mark the 30th anniversary of the music legend's death. Lisa Marie's voice was added to the original version of her father's hit song In the Ghetto for the new video, which also features images of her late father. And the 39-year-old is delighted with the tribute to her father. She says, "We had two hours to lay down my vocals. So the next morning, I heard the rough (edit) and I've never cried when I've done anything ever... but I just lost it when I heard it." The video - posted on Spinner.com - will be put online along with the transcript of an interview with Lisa Marie. Presley died on 16 August 1977, aged 42.
