Opening the show was a group performance by this season's Top 8. It wasn't one of the best group performances I've seen on The Voice, but it was okay. The three guys left started the piece off, with the girls coming in for the second half. It may have just been me, but it seemed as though the girls were trying to 'one-up' each other with there solo parts... a theme that sadly seemed to carry on into the competition part of the show.
