SUN VALLEY SERENADE was a surprise and a big success when it came to Europe, and I don't understand why ORCHESTRA WIVES did not travel well over the Atlantic (to my knowledge). The musical numbers are quite a few, and Lucien Ballard did a tremendous work at filming them. The Nicholas Brothers are even better than in the former Miller movie (and they were at their climax the year after, in STORMY WEATHER). The plot is unessential, as in most of the musicals, but the "wives" are all good looking and the players are credible too. Special mention to singer Marion Hutton, sax player Tex Benneke and drummer Moe Purtill, all uncredited.henry caraso
