Can they make Matt sing this on Glee?

[HeatherKay13]

Excuse me Matthew Morrison but can you please shut up and let Jc sing! Thank You!

[deraldino]

in the beginning when I started watching glee, I thought it was Justin.

Matthew Morrision remember Justin

[tanygrimiran91]

this made me shed a lil tear :') nsync was good but i always had a soft spot for jc he had the best voice in my opinion

[yosemitetony]

Matt should stick to tv...but he can harmonize. Jc is awesome!

[kitkatprof]

I wish JC would go back to singing. Ive heard some of his stuff since NSYNC broke up but i havent seen alot of it around

[bellajacklil]

Im so use to hearing Justin sing those parts, but matthew sounds awesome too! AND MAN!!!! JC SOUNDS JUST AS AMAZING AS ALWAYS!!!!!

[mainechickie11]

that was amaze-balls! Matthew Morrison pretty much killed it! but the addition of JC Chasez sealed the deal and made this song amazing! Justin who?!? lol!

[mainechickie11]

that was amaze-balls! Matt Morrison killed that song and the addition of JC Chasez just makes it even better!

[Monkey7Sees]

No offense, but you can step aside Mr. Morrison. Pretty sure Mr. Chasez has just stolen it. <3

[obsessed4jc]

Great quality & sound. Thanks for sharing!

[LudvigXIV]

[crazzieoverjesse20]

[DiemSiobhan]

13 years later and JC Chasez still makes my heart flutter.

[abesdude]

@DiemSiobhan wow has it really been that long? It seems like yesterday that Nysnc were together. Still till this day there has never been another group like them. Dance and sing at the same time and still sound great doing it. Totally miss Nsync.
