It's kind of a tribute to Las Vegas where their "Achtung Baby" residency at the NEW "Sphere" has begun. You'll also notice a very close similarity to another song from the "back in the day" files. "Call Me" from Blonde. I'm guessing so close they added Debbie Harry and Giorgio Moroder get co-writer credits. BTW, "Call Me" was originally written for Stevie Nicks but her label would not let her do it. Debbie Harry took it, re-wrote it, and got the score for the "American Gigolo" soundtrack.
