The Sing Off 3 - 10th Eliminations

Well after some performances with their ups and downs the judges decided which group is going to be sent home..though i thought this battle of the bottom 2 groups thing was gonna be the norm but that was just a one time thing unfortunately..too bad about that.

But will it be Afro Blue? Vocal Point? YellowJackets? Delilah? Pentatonix? Dartmouth Aires? or Urban Method?
Did the right group go?

The eliminated group sang "Tubthumping" By Chumbawamba
i really liked the way they left the stage lol, so much enthusiasm and with the lyrics..but what's with that guy and his arms folded as they left??
