I don't consider "Walk Like a Man" to be a Broadway song at all. It existed for a long time before getting used in a musical. The same way I wouldn't consider ABBA songs to be Broadway songs after Mama Mia came out.
I have a feeling Maks won't be asked back next season. It's one thing to stick up for his partner but to criticize the panel for judging? What does he think they are their for??? It's their job to point out what contestants are doing right and what they're doing wrong so they can improve. It's not personal.
I feel sorry for Tristan being stuck with nasty Nancy. She tells him they need to step it up and when he gives her more to work with, she accuses him of sabotaging her! Did it ever occur to her that if she's voted off, his time on DWTS ends, too, so what could he possibly gain from sabotaging her? I actually wouldn't mind Nancy going before Chaz at this point because he's at least respectful to his partner and making an effort.
