From 1980, and the most excellent Urban Cowboy soundtrack.
This is the song that is playing in the background when Bud cheats on Sissy with Pam. A gorgeous backdrop of Houston, circa 1979, is seen through the ceiling-to-floor windows in the apartment, as Pam turns on her stereo and lights those curiously skinny candles.
I hear this tune a lot at Safeway, and I usually stay in the store and shop so I can hear all of it. That is, unless it is marred by "Larry, I need cashier service up front, please!"
