FUNNY GIRL's cast of 43 was reduced to 22. A 14 piece orchestra replaced the original orchestra of at least 24. The brass section n Chris Walker's orchestration (and he is a great orchestartor), is 2 trumpets, a trombone, and a french horn. Originally it was 3 trumpets and 3 trombones. There are currently 3 reed players. Originally there were 5. Today one percussionist, Back then, 3. Today 2 keyboards, 2 violins, cello and bass. Then a full string section. It makes a difference.
Thanks for all of this. Those of us without the musical knowledge could only question whether it's mediocre amplification or some technical issue. I had heard the orchestra was cut down, but found the sound in the Wilson -- starting with the iconic overture -- oddly loud and yet seemingly underperformed. Now I know precisely why.
