Zey-Zia,
Probably Lisa needs more time to gain perspective of herself in the sense you are talking about -what is hers and what comes from a discipline she has gone through. The interview was done some time ago, too.
Quote:
Back in 1997, you did a video shown for an Elvis Tribute concert in Memphis where you’re doing a duet with your father on “Don’t Cry Daddy.” How did that come about?
I did that because I was tired of being some figure that just comes out, smiles and waves and leaves. I was asked to appear at the tribute concert. I said I’d come. I had this whole vision on this airplane. I think I was flying from New York to Florida and oddly enough I was in the bathroom (laughs) and I had this whole vision. I was gonna call David Foster and I knew the song. I was on the plane and I was thinking about it and I started getting emotional with of the idea. I definitely had that relationship with my fad where I felt a lot of pain and I knew that song would be very meaningful. I loved the song. I called David Foster and told him he needed to produce this thing for me, that it was only a one-time deal. I’m not selling it, I’m not selling out but I just wanted to do something for the fans that night that was something special. David said he’d do it. That was kind of the beginning of the whole deal. It was only done for the fans for that one night. Believe me, that could have been packaged and sold. It actually turned out pretty good I thought.
I have looked for the link to the video in YouTube where Lisa was singing that song with her father, with the intention to post it for the newcomers, but it has been removed! I'm so, so sorry... I loved to view it now and then. I didn't know how to save it and now it's lost! That video is really a TREASURE.
ok.. I became a demanding big sister to her ,for today
