SERIES PREMIERE: Watch and record this, because it’s a little piece of instant TV history. It’s the first time The Tonight Show has emanated from New York since Johnny Carson departed for California in 1972, and the first Tonight Show hosted by Jimmy Fallon – performing in the same 30 Rock studio that once housed Carson and, before him, Jack Paar. Tonight, Tonight starts another chapter in its long, impressive history, which began nationally on NBC in 1954. Opening-night scheduled guests: Will Smith and U2.
