New British game show Sing If You Can, described as Wipeout of singing competitions, is close to finding an U.S. TV home. Zodiak USA had already been pitching an American version of its format, landing two offers from U.S. networks. Then the series premiered on ITV on Saturday, Britain's highest-rated TV night, with 5.4 million viewers to rank as the network's biggest unscripted series premiere in 2 years.
