Those in the U.S.A. have probably seen this, i onyl just got sent it, and thought it was awesome

Celine Dion appeared to walk out and stand next to Elvis as the two sang a duet of the classic "If I can Dream." It was like he was raised from the dead. Totally amazing what they can do now. Estimated cost of this was said to have cost between $50,000 to $100,000 and it is said it took months and months to create. Prior to the performance, Celine practiced with an Elvis impersonator. However, it was done, it was totally amazing to me. She sounded great singing with Elvis. The duet was fantastic. Celine Dion in front of a LIVE Studio Audience. This is absolutely unbelievable how they have done this. It really - really does look for all the world that Elvis is actually standing there live on stage singing along side Celine Dion in front of the live American Idol audience. Watch and listen to the audience going berserk, as they themselves think they are actually seeing Elvis right there in front of them. A truly amazing use of modern day technology....
