I've cogitated for some time this week as to why the National has only sparse information available on the 1974 American tour.
Let's go back to the beginning: a couple of years or so before the 1974 opus, Sol Hurok, impresario of New York's "Hurok Concerts", imported an "all male cast" production of "As You Like it," which produced excellent revenues at the box offices around the United States. In 1974, Hurok Concerts thought they'd like a second bite of the apple; however, the novelty of the "all male cast" had seriously soured financially. In particular, Clive Barnes (from England), the New York Times ballet critic, gave the play a poor review, so after a single week at the Mark Hellinger Theatre, they canceled the production. The Musicians Union stepped in and made sure we were paid until the end of the tour some weeks later. Hence, I'm certain that this was technically an American production, because Herman Shumlin and his wife Diane controlled the finances for Hurok Concerts, so they were essentially the producers. I don't think the Royal National Theatre considered this, or the prior production, a bona fide event for the record books.
