From the xmasprompts list on tumblr (it's the name of the blog) Set after the show.
Reeaaally short, and, yeah, I had to talk about Hamilton… ;) You don't have to know the musical, but I recommend you to listen to it because it's great! (That situates the fic in 2015 or anytime later)
Day 11: Musicals/song
Chandler studied the CD in his hands, unsure. Erica had left it on the table for him, saying she recommended it. It was the first musical she advised him to listen to and he hoped he hadn't messed up her musicals education. She knew all the classics, and the less classics he loved. They often sneaked out and watched one when they could, especially when Erica was younger.
And now, he was about to test if he had succeeded as a father – yes, it was that important. That Hamilton thing looked interesting, and he would probably get most historical references – he remembered vividly the detailed presentation he had to do about the War of Independence. He had liked studying it.
"So what did you think?"
"Shh!" he gestured to Erica.
He was in the middle of his third listening, and the lyrics were starting to get into his head. When Erica grinned, then started singing, Chandler joined her, even if it sounded wrong because he didn't know the lyrics yet. Monica and Jack tried to calm them down, but after a couple of days, they were all humming the songs pretty much all day long.
