After Fox aired its spring preview of their new musical comedy Glee, viewers couldn't stop buzzing about McKinley High's "gleeks" and their high-octane version of Journey's "Don't Stop Believin'".  

With the series gearing up for its full freshman run (starting Wednesday at 9/8c) with new songs and guest stars including Kristin Chenoweth, Victor Garber and Josh Groban, TVGuide.com caught up with Matthew Morrison — who plays the high school Spanish teacher-turned-Glee Club director, Will Schuester — to get the scoop on what's to come, his ad-libbed scenes with Jane Lynch and all the rapping he'll do this season.

TVGuide.com: The pilot had a lot of energy and spirit. How will the rest of the season maintain that kind of zeal?
Matthew Morrison: There's a certain amount of camp involved in the show. The reason we get away with so much stuff is because we don't take ourselves too serious, and that's going to keep going. There's actually one episode coming up called "Vitamin D" and it's all about people taking these upper vitamins — so that episode definitely has the energy. [Laughs] But Glee rides a great line where there's this amazing energy but [it] also has these deep emotional moments as well.

TVGuide.com: Some of the best scenes are between Will and Jane Lynch's hardcore cheerleading coach character, Sue. There has to be some improvised banter in there, right?
Morrison: We go in with our lines, but with Jane and I, they really let us go. A lot of what they keep for the scene is our ad-lib. There's an episode called "Smackdown" and it's her and I going at it like you've never seen two people go at it before. We have a lot of great stuff together. Those scenes are so much fun to do, except I have to try not to laugh.

TVGuide.com: Will also has a teacher crushing on him pretty hard. What do you think will come of that?
Morrison:
There is this budding romance there, but Will is a very straight-arrow kind of guy and very family oriented, so that's his number one priority.

TVGuide.com: But how can he possibly put up with that awful wife of his?
Morrison: [Laughs] It's hard trying to defend that relationship. I don't think she was always like that. They were high school sweethearts and [she's] the only woman he's pretty much ever been with. He really wants a family, so he's able to look past all the craziness she has. I think that's one of the best storylines of the show. She's pregnant now and there's a lot of stuff that's going to happen with that which will make it really, really interesting.

TVGuide.com: Glee is one of the most anticipated shows of the season. Other than the singing and dancing, why do you think it resonates with viewers so much?
Morrison:
It's such an original show. Every now and then, I think there's a show that's just so fresh and you can't compare it to anything like a cop show or a lawyer show. It's its own thing and that's what makes the show so appealing. And there's so much optimism at a time we need it. It's a true underdog story and we've all been the underdog at some point in our lives.

TGuide.com: We saw the preview of you rapping to Kanye West's "Gold Digger" with the kids. What other songs can we expect to see featured this season?
Let's just say "Gold Digger" isn't going to be the last time I rap. They kind of threw that in there and were really excited I rapped, so I have another one coming up. I'm going to bust a move a little bit — hint, hint.
