But in the end, Don makes his first steps to admitting who he is: with his kids, including the troubled Sally, who witnessed firsthand her daddy's inability to keep his pants up. He takes the kids to the dilapidated, falling-apart Pennsylvania whorehouse where he endured his awful childhood. It could be his first steps to permanent redemption. Maybe.
And at the end: a song that was heading for the Top Ten (peak position # 8 in Billboard) at that very moment: Judy Collins's Grammy-winning rendition of Joni Mitchell's "Both Sides Now," the biggest hit the veteran folkie had in her entire career.

And frankly, it was the perfect song to close out Season Six.
