So many good scenes. Johnny Cash's memorable line in the airport scene in Swan Song, "Columbo, are you following me?" was shown at the legendary Cash's funeral.

That's neat, JenSam. I hadn't realized Cash's stint on "Columbo" got referenced in the aftermath of his passing, but it's great that it did. He had such a wonderful presence in that episode, and for me he out-performed some of the more professional actors from other episodes. I'm not sure if Cash was a fan of the show, but it wouldn't surprise me if he had at least some emotional connection; he seems to have such a grand time playing off Peter Falk.
