Also agree about the sound issues - I was near the front of the orchestra, I couldn't hear most of the Pharoah song and I had to strain to hear some of the singing over the music. Still, it was some of the most fun I've ever had in a theater. I was lucky enough to see Bonnie Milligan in the one-night "Camelot" last year, too, and now after hearing her "Canaan Days," I wish someone would give her her own show. Brooks Ashmanskas and Gavin Lee were also incomparable, and I was a big fan of the Andy Karl/Trump imitation, wish it was on video! Also, I found the flubbed lines charming.
BTW, there ARE videos of the Megamix all over Instagram, and Bonnie posted one of Canaan Days, too.
I was not into the sequence where they held up signs with names -- I understood "Joseph," "Greta," "Martin" etc. but got confused by "Harvey." Didn't realize until I read the Vulture story that they meant Harvey Milk!
