It's all down to the viewers this evening as the final eight become just four and Vangelis confessed that picking one killer song to perform live had been difficult.
Last weekend he wowed with a cover of Here Comes The Rain Again and trying to replicate that success has put the pressure on Vangelis.
"I’m literally the worst person at choosing songs," he admitted this week. "George has his ideas and I have mine and we kind of clash a bit, particularly this week for the song.
"I think it’s just best to be honest with each other."
While Vangelis couldn't reveal his song choice for tonight, he did tease: "This week it was really hard because I didn’t think I would get through so I wasn’t preparing stuff, but it’s a song that is challenging this week vocally as well as lyrics wise."
This evening will also see the remaining acts sing with their coaches for a group performance as Vangelis shares the stage with mentor George and team mate Cody Frost.
Speaking to GT, Vangelis revealed of the planned group number: "We had a rehearsal the other day and he was on stage and the focus was all on us.
"I suppose for him, it must be strange having to come up and sing. When you’re a coach, you must feel like you have to prove yourself. There’s probably going to be nerves from both of us so it will help us to just go for it."
He added: "We’ve got a really nice song so I think people will enjoy it."
The Voice UK 2016 airs tonight at 7PM, LIVE on BBC One.
