The Glee cast is so ridiculously talented. Though it seems slightly odd that they had Kristin Chenoweth guest star in an episode and didn't find a way to have her as part of this number (since she was the original Glinda). - Dan Hsiao

Yeah they are great. We saw Lea Michele (Rachel) in Spring Awakening about a year ago. She was very good (the whole musical was). - Benjamin Golub

@Dan - I think the main difficulty there was that Kristin Chenowith's story arc lasted only that one episode, and the episode that this number is in hasn't aired yet. - Brian Chang

Yeah, it didn't really fit in with the way her character was written... but I also feel like they didn't necessarily pick the best pieces for her. How awesome would it have been if she did "Popular"? Anyway, I'm really behind in this show so should find time to catch up :( - Dan Hsiao

I really liked the duet they did together, I think it was Maybe This Time. But it isn't really fair making anyone go up against Kristin Chenoweth - Benjamin Golub

I dunno... i feel like Lea Michele sounded better than Kristin in their duel... Lea Michele's voice is freakin' amazing. - Dan Hsiao

Dan, did you see them perform the national anthem at the world's series? - Jeannie Choi

I did on YouTube. :P Link for those who missed it: http://www.youtube.com/watch... - Dan Hsiao

I was impressed. The songs on the show are very over produced, you know? So I was skeptical about their actual singing talent, but wowzers, they can sing well live and a capella, not an easy feat. - Jeannie Choi

Agree Jeannie - why do they have to super-synthesize the songs on an otherwise fine show? it's hecka annoying - Felicia Yue
