It was Chromatics who played the backing band for Cruise and in fact played live with her. I think maybe one of the issues was that they wound up using the original recording instead of what was played. Who knows why. Jonny Jewel said in a P4k interview that they practiced it over and over; and they did one take, then Lynch whispered something to her, and he didn't know what it was, and it completely changed the performance and the second one was amazing. Clearly that wasn't what was used in the end.
