Pentatonix on Great Day St. Louis 

I love how they pronounce Avi's name wrong and they starg laughing

I live in St. Louis HOW THE HELL DID I NOT KNOW ABOUT THIS

WHY THE CUT OFF????

Sound quality doesn't do Pentatonix justice! But good for uploading to share :)

Omg Avi he looked like he was going to correct them when. they said "Ayvee" but they kept talking so he couldn't

ahhh CUT OFF??!!

They corrected themselves anyway though.

They asked if it was right.
