"Nightsong" is the second segment of the twenty-seventh episode (the third episode of the second season (1986–87) of the television series The Twilight Zone.

Nighttime radio disc-jockey Andie is in a funk after a short relationship with a fellow D.J. One night she discovers a record in her library by a former lover, Simon Locke, whom she broke up with five years earlier. She finds out that her fellow D.J. is the one who discovered it and thought she would enjoy it.

However, after starting the track from the album "Night Song" during her shift, Simon shows up at the station. She confronts him angrily about how he walked out on her and never came back. She then turns and he's gone. When leaving the station after work a motorcycle almost hits her, but Simon saves her in time. He then follows her after she discovers her car won't start, and they begin rehashing their relationship.

In a coffee shop Simon and Andie discuss their past and she questions why he hasn't produced anything since they broke up. They discuss the good and bad times of their relationship. She suddenly realizes she doesn't want to get played by Simon again so she leaves the cafe. At home, she can't seem to get away from "Night Song" as she finds it playing on her stereo. She then discovers Simon and talks to him again, but this time about how his songs detailed their relationship. He attempts to seduce her but then stops and says that they can't have their relationship back and while she's angry he tries to explain why they can't get back together.

Simon takes Andie toward the ocean on a back road and he tells her that maybe he was running from her or success the whole time. He careens off onto a dirt road and they stop to get out near the edge of a cliff. He takes her down the hillside and he tells her how when she played his song he decided to come back to explain to her what happened. Then, he pulls back some brush to reveal a wrecked motorcycle and a skeleton. It is revealed that Simon had died in a motorcycling accident years earlier. Afterward, she goes back to work and gets a call requesting "Night Song." She plays the tune with the dedication "from Andrea to Simon with love."

The song, "Night Song" was written by Stephen Stills and Neil Young, and performed by Stills. The song, with additional overdubs, was included as the last track on the 1988 Crosby, Stills, Nash & Young album, American Dream.
