What Music Video Is This Picture From?

Many believe the video that this picture comes from is the greatest music video of all time, in any genre of music. It's been called just that by at least one publication, with several others including it in their Top 10, 20 or 30 lists. Do you recognize the video? You'll probably get it if you know who this woman is. 

She died just three months after filming her part in her husband's music video, and he'd die four months after that. Images of this man's youth are spliced between shots of his appearance at age 70. The song was originally a rock song, but even the songwriter agrees that once this video was created, it ceased being his song. A country legend took ownership.
