| by Michael Allen

After a long summer vacation, McKinley High is back in session on Tuesday night when Season 3 of 'Glee' premieres on Fox. But you don't have to wait that long to get a glimpse of the episode; several clips from the premiere have been released (video below).

At a recent preview screening, co-creator Ryan Murphy talked about getting back to basics with the show with more focus on the core group of characters and the show and less about movies, products and mall tours.

"Things took a bit of a nasty turn," Murphy admitted when talking about Season 2. "Frankly I think the fans resented it."

After announcing the departure of main stars to make room for new blood, then back-tracking earlier this year, Murphy joked: "I will never again say people are leaving. I've learned my lesson, never again!"
