When TV Land recently began showing reruns of "Wyatt Earp," I had forgotten that, apparently in the early episodes, the only music heard was an a cappella male quartet. Not only did they sing the theme song, but periodically during those episodes, to augment certain special "drama," they would chime in, humming either low in the background for sentimentality, or swelling to full volume when the emotions were supposed to be at peak. The only lyrics heard were those of the theme song; otherwise, the musical accompaniment consisted entirely of that periodic humming in four-part harmony. Written out, it appeared, "mmmm-oooooo-AAAAHHHH-OOOOOHHH!!" Bypassing a full orchestra was one sure way to save a chunk of cash for the budget. Then in other, perhaps later, episodes, orchestral music replaced that humming, and the a cappella quartet only sang the theme song. I must admit that the humming contributed a rather corny element to the show.
