Vanilla Fudge, 'You Keep Me Hangin' On' (Season 7, Episode 1)
Speaking of Don's loneliness, the season seven premiere ends on a pretty bleak note — and not just for the show's hero. (Although the image of him sitting on his balcony in the freezing cold, seemingly in the middle of a breakdown, is pretty bad.) After butting heads with SC&P's new creative director, Lou Avery, and being reminded of her disastrous affair with Ted Chaough, Peggy breaks down sobbing on the floor of her Upper West Side fixer-upper. Vanilla Fudge's plaintive cover of the Supremes hit song, plays the episode out, and damned if it doesn't speaks volumes. "Why don't you get out of my life/And let me make a new start?" could just as easily apply to Don and SC&P, or Peggy and Ted, or Peggy and Lou. Take your pick.
