Glee: Neil Patrick Harris talks guest spot, working with Joss Whedon again...

I was on set for the filming of tonight's episode of Glee , which was directed by Buffy the Vampire Slayer creator Joss Whedon and featured Neil Patrick Harris ( How I Met Your Mother ) as Will's old rival Bryan Ryan. In between takes of Bryan and Will's dynamic cover of Aerosmith's"Dream On," Harris sat down with me to talk about guest-starring on the Fox series, working with Whedon, and the Glee character he finds "dreamy." (For those of you who haven't seen the episode tonight, a mild spoiler alert warning!)

'Glee' Spoilers: Who's Singing What on 'Dream On'?

Next week's Glee is a pretty big deal. We've got Neil Patrick Harris on board. We've got Joss Whedon directing. And judging from the promos we've seen so far, it seems we'll finally know whether Jesse really feels something for Rachel or if he's really just sabotaging New Directions. I just got my hand on that episode earlier today. Yes, I've seen it. And yes, I can tell you which songs are featured in next week's episode, called "Dream On." Sure, most of the songs have already been revealed, but who's singing what? Read on. I'll be sneaking in a couple of details in between, too. To Read More Click Here .

Glee' Episode 19 Promo: Already obsessed with 'Dream On'?

Confession: I may have rewound the promo for next week's episode of Glee , featuring Neil Patrick Harris as Matthew Morrison's old rival and current nightmare, three times. And when I say 'the promo,' I really mean just the three seconds of Harris and Morrison belting 'Dream On.' That number has a lot to live up to: According to PopWatch polls, Harris was by far the Glee guest star readers were most looking forward to in the second half of the season, and this duet was the most-anticipated number. I find it sort of odd that the promo didn't mention that the episode is directed by Joss Whedon, but perhaps Fox thinks anyone that matters to already knows. Watch the promo (again) after the jump. How many times did you rewind? How confident are you that 'Dream On' will end up being as awesome as Harris' flashback mullet? Source & Promo
