Vanilla Fudge
1It seems like nobody noticed this back when the Mad Men Season 7 premier first aired, but the song playing at the end of the episode is "You Keep Me Hangin' On" by Vanilla Fudge, which was used twice in the final episode of Sopranos - first in the opening scene, and later during the Phil Leotardo whacking scene. Interesting little detail, I'm sure it's no coincidence that Weiner chose this song.
Taps, lights out, 2200 hours. What's missing? Give up? Television.
