With all respect to the artistry of Mr. Doyle, you should expect to see more of Mr. Doyle's productions on Broadway because they are much cheaper to stage than a traditional musical. When you do away with the orchestra and have actors-musicians, you save MILLIONS of dollars.
Over the last 10 years, orchestra sizes have gotten smaller and smaller on Broadway. Revivals are now done with reduced orchestrations and shows like Urinetown and Spelling Bee only have 4-5 instruments.
Now that Broadway producers have discovered Mr. Doyle, they can help their bottom line by having productions that eliminate the orchestra all together and allow them to recoup their money relatively quickly (19 weeks I believe for Sweeney Todd-- Normally it takes over a year to recoup an average musical on Broadway).
After Company comes to Broadway, get ready for Mr. Doyle's UK version of "Mack and Mabel" or maybe they will ask him to direct "A Little Night Music".
With all respect to Mr. Doyle's artistry, nobody else on this board seems to decry the decline of the Broadway orchestra. Having seen shows like "Sweeney Todd", "A Little Night Music", "The Most Happy Fella", and "On the 20th Century" with the original full orchestration I find it very hard to see them any other way.
Am I the only one who misses the large Broadway orchestra?
"It does what a musical is supposed to do; it takes you to another world. And it gives you a little tune to carry in your head. Something to take you away from the dreary horrors of the real world. A little something for when you're feeling blue. You know?"
