I believe that was Billy's tribute to "The Righteous Brothers."
That’s what I like about Billy Joel. He doesn’t shy away from “tributes” to legends. Listen to “An Innocent Man”, and you can pretty much name every group he’s honoring with nearly all of the songs on that album.
Same with “The Nylon Curtain” A lot of Beatles in that album (”Laura”, and “Scandinavian Skies” come to mind.
