I regret to report that I went to the Sacramento Music Circus to see Cats and had a wonderful time. In fact if you are going to see Cats, it should definitely be at the Music Circus.
I feel that Cats is best understood as a ballet on a poem by T.S. Eliot. After all, all sorts of nonsense goes on in ballets. If swans are OK, why not cats?
There were a couple of older performers, at least I presume they are older, who sang virtually without reference to any particular pitch. I pretended they were cats.
Outside the theater were real cats from the SPCA.
