TV commentary:
Rent- Didn't get to watch this live. Its really unfortunate the Roger guy broke his foot and they had to use the dress rehearsal footage for most of it. Seriously, no understudies? Like yes, I'm sure if Vanessa Hudgens had been the one unable to perform, the audience would be disappointed if they got some rando instead of her. But she's prolly the biggest star in the cast.
Like no offense to their Roger, but he's prolly one of the least famous people in the show- I'm guessing after Vanessa, its a toss up between Jordan Fisher and Valentina, then "that lady from the Greatest Showman" (yeah I know her name, but I bet that's what most people said when they saw her in this. And she's not even playing a main character!), then Kiersey Clemmons and Tinashe, and then the rest of them. But yeah, they shoulda had backups. Wonder if they'll start to in the future.
Anyways, its disappointing because the show didn't get a fair shake. People will always wonder, what if the guy didn't break his foot and they got to perform for real.
But since I'm more used to the movie soundtrack, I forgot there are other songs not in the movie, and some songs that are different- the movie version of La Vie Boheme doesn't have that Maureen/Joanne stuff. Also, I'm surprised how much of the lyrics I actually know from the soundtrack and found myself singing along. (Which, as much as I love the Tom Collins' songs, I do not have the voice for them)
Heh, the last act was live, and you'd think if the Roger guy already has all this hanging over him for breaking his foot, he'd do a better job when they started performing for real. But like Maureen and Joanne come up the stairs with Mimi and he's like "NOOOOO!", but in a very deadpan manner:

I kinda cracked up at that.
Arrow- Pretty clever!
