For video DJing, especially playing classic rock videos, I often have had to make videos for songs that don't have one. Sometimes I use found footage that goes with the song, sometimes I have to splice together live clips of the artist and try to match them to the studio version of the song. Then there is The Cars, which pretty much played songs live EXACTLY the same as the studio versions, vocals included, give or take playing slightly faster or slower. This clip is proof, it required maybe one or two edits and I had to change the speed slightly to have it all match up.
