As supporters' excitement builds in anticipation of the presidential conventions, a new video has hit YouTube featuring clever editing of Barack Obama "singing" to Rick Astley's 1987 hit "Never Gonna Give You Up" -- a clip that has now attracted over 1 million viewers.

The video plays off the Internet trend of spreading Astley's video to unsuspecting viewers, a practice known as "rick-rolling."

Hugh Akin, creator of the Obama/Astley video, wrote on his blog that the video took him "a number of days" to produce and that he used Google's Election Video Search gadget to find all the different clips of Obama speaking.

Akin posted one video with just Obama and another version with a side-by-side comparison of the Obama and Astley videos.

"The dancing really is quite similar," Akin said when comparing the two.
