Musical Eras & How it Affects Their Story

I just had an idea for an AU fanfiction, but I suck at writing, so someone should pick this up. It's only the Laendler part. So basically, the party is taking place, but it's the 70s, so instead of an orchestra you have some kind of DJ using records of Disco and Rock music. Maybe instead of a ballroom and patio, the Villa has some kind of dance floor room setup specifically for parties like this. I envision that Georg used dancing in clubs as a way to move past his wife's death *cough* drinking *cough*, while all the Governess's were at the Villa struggling to wrangle his children. This would be before he met Elsa, so he would have become an exceedingly good solo dancer within the Disco scene. I imagine most of the people there would know that and give him his space if he wanted it. I could see him pushing away from Elsa when The Bee Gees 'You Should Be Dancing' comes on and taking over the whole floor. Maybe the children are in another room with Maria working on the YMCA for their performance? That's the only thing I can see replacing So Long, Farewell that's from the 70s. If anyone else has something better, please tell me! LMAO! I see it being that Maria comes in after their practicing and catches the Captain dancing solo and of course, goes red in the face, not sure of what she's feeling. We all know what Disco dancing looks like, so for a postulant, it's a little much to see. However, I think Maria, being mischievous, has probably snuck out and seen dancing and heard the music in clubs before, perhaps even participated before somehow and become quite good. This leads into the next part. When Georg's solo song ends, he's probably a bit tired and needs a good drink, so he'll go take a seat with Max, who will give him a good hardy pat on the back. Then we'll hear Maria's favorite song. Once when she snuck out, she happened by a Disco club and heard a particular song that she could never forget; now that she's hearing it again she wants to dance, but someone might catch her! Who's she kidding, no one pays attention to the Governess anyway when they have a partner! She sneaks into the middle of the dance floor to The Jackson 5 'Dancing Machine'. She's surprisingly confident in her dancing for a postulant, and somehow no one has taken notice of her. Well, except for someone at the bar. Georg spotted the blonde hair and her dress. He couldn't believe his eyes. She's dancing, and she's... she is amazing! His mouth went dry, and Max happened not to notice as he ordered a cocktail for himself. Max snaps Georg back to the conversation. After the song ends, Maria begins to try to sneak away as the next song begins Earth, Wind & Fire 'Got To Get You Into My Life', but Georg catches her first. She looks up at him in terror, afraid she has angered him by participating. Instead, he takes her hand in his and leads her to a more secluded part of the dance floor.

And that's where the idea ends.
