The opening number was not botched, it was perfect. The sound was botched. Has happened to me and my groups hundreds of times.
It can be many things from technical to accoustics, etc. etc.
Basically that’s what I said in my first post: Billy was funny but the sound guys messed up.
Maybe you missed reading it.......
And I did expect near perfect sound from the opening number of the Oscar broadcast. Maybe I expect too much from “the best.”
