I know something about it...if I'm not wrong it was a TV special at NBC hosted by Chris Isaak to celebrate the 25th Anniversary.
There were interwiews to many artists (singers and actors) as Kevin Bacon, Bono, Dennis Hopper , Cher, Britney Spears, Naomi Campbell, Steven Tayler, Bruce Springsteen, B.B. King, Sarah Jessica Parker,president Bill Clinton ....talking about Elvis, his career and his important role in music at that time but also nowadays, his legacy for contemporary performers.
There were also live performances: Chris Isaak&Leann Rimes singing "Devile In Disguise" , Norah Jones - "Are You Lonesome Tonight", No Doubt - "Suspicious Minds" and many others.
I had the occasion to watch it and I found it quite interesting... a nice tribute to the King.
