Yeah, I went looking for it on Back To The Egg. Columbia (or McCartney) were morons for not including it. I loved the song as a kid, but now I recognize it as another pop/rock fossil climbing aboard the disco bandwagon. Like "Da Ya Think I'm Sexy" it certainly works, but unlike "Sexy" McCartney feels like a bizarre fit on the dance floor. Whereas Rod sounds like he was born to front sleazy (or maybe not!) disco songs. "Goodnight" is sort of a discofied "With A Little Luck" - slight melody, spacy rambling instrumental noodling, pulse provided by electronics and Paul's bass. He was headed fast toward the end of his commercial relevance. You can only fly on vapors for so long.
