I'm a keyboard player and MD, and recently put this together with the cast and band of a show I was working on this winter (we were supposed to have opened on April 2nd, now indefinitely postponed, likely until next April). I am far from a pro producer, but I did the audio mixing (and played tracks for the band members who couldn't participate; drums, keyboards, cello, one trumpet), and someone else did the video.
That is so amazing!! I'm an absolute sucker for musicals, so add Tim Minchin to the mix and I'm hooked. Great job! Has anyone attempted to let Tim know about this vid?
