U2's brand new single, "Window in The Skies", features footage from the Stage Show (1956) and de '68 Comeback Special. The technically amazing clip shows Elvis actually singing to the song. Other artists play a part in the clip too.
There are two Elvis clips - one from one of his Stage Show apperances in 1956 and one from his 1968 TV special. The EPE site mentions: "It was indeed our pleasure to cooperate with U2 on including Elvis in this great new music video".
The clip is available on YouTube: http://www.youtube.com/watch?v=VskbxuehP3I
