"They still talk about 'Vegas throat.' But, really, 'Vegas throat' just meant no sleep. I'd stay up all night and the next day get up and play tennis, go to the lake [Lake Mead] to water ski and just generally have fun. That's what hurt the voice. Today Las Vegas is different, so built up, that people don't do it like that any more."

Today, one's throat can still be affected by the desert weather, although the AC has gotten a lot better. Enge is vigilant about caring for his voice and, among other preventive measures, uses Vocalzone, a lozenge made and sold in the UK that was originally developed for Enrico Caruso.
