Very sad news. (May they rest in peace.)
You make a good point that at least they will now be spared the pain that most older couples eventually have to suffer through, with one going first, and the other one left behind. This song illustrates that kind of heart-wrenching sadness, and at least that poor couple in DC will not have to face that pain now.
