I did watch NAKED BOYS SINGING tonight. I found it slight, simple, and occasionally sweet, nothing to get excited about certainly, but I was engaged somewhat by the material and the talent of some of the cast members.
My biggest disappointment was that even though the show was filmed during four live performances, the vocals were post-dubbed which gave a very artificial and "dead" quality to the show. Some of the voices were really mediocre (read screechy), too, but I did think a couple of the guys had real charisma and genuine talent (leaving aside the nudity.) (The guys who sang lead in the bris number and the "I Had the Radio On" song were my favorites.)
