One of the many topics in regard to which I heartily agree with Mr. Ethan Mordden (novelist, raconteur, and entertainment historian
par excellence) is the regrettability of the extent to which Hollywood (and, to a lesser extent, the stage) embraced the idea of the New Dance Sensation Number. This surprisingly long-lived phenomenon consists nine times out of ten of a (frequently quite lavish) sequence based on a (nearly universally) sub-par song in praise of said terpsichory, staged without even a hint of what the damn dance was supposed to actually
be. I mean, face it - based on what you've seen on screen, could you attempt to dance the Varsity Rag? The Continental? I thought not.
Along those lines, this one's a lulu - and that's the least of its (many) sins.
