1st Performance - Pentatonix - "ET" by Katy Perry Ft Kanye West - Sing Off - Series 3

I'm surprised the girl wasn't the main singer of the group given there's 4-1 in guy/girl ratio lol but the guy is actually a good singer..and this song actually worked very well. A guy singing a girl song doesn't turn out good in some talent shows but this one did but i wonder if the group will be hindered later on with such small numbers compared to groups that have a lot of back up and it showed in the middle...B
