Some last-minute tinkering of NBC's prime-time schedule will flip two new Wednesday-night comedies this fall: "30 Rock" and "Twenty Good Years." "30 Rock", with Tina Fey, will now lead off the night,
followed by the John Lithgow-Jeffrey Tambor comedy, "Twenty Good Years." Analysts say there is better buzz for "30 Rock" than "Twenty Good Years.' NBC wants to start the night with a show that has a
stronger chance of success.
