New York’s newest voice Thirty Rockefeller Plaza is getting more melodic, as “The Kelly Clarkson Show” moves across the country from Los Angeles. Clarkson’s talk show will now reside in 30 Rock’s Studio 6A, across from “The Tonight Show” and a couple of blocks away from the theater district. The Emmy-winning program, which snagged 11 more nods this year, will surely benefit from New York and Broadway’s musical talent as it relaunches in a different key.
