Vince, who is good friends with Mitch Winehouse, run the song choice past him before performing the track.
"Doing Back To Black wasn’t what people were expecting but I just chose one of my favourite songs," Vince explained. “That’s one of my favourite albums and she’s my favourite artist. I’m friends with Amy’s family so I asked Mitch before I did it if it was OK and then he texted me afterwards and said he was really proud.”
The track won Vince a spot in this weekend's final, where he'll be competing for a record contract with Universal music.
Vince also revealed he checked the song choice with Amy Winehouse's former boyfriend Tyler James, also a contestant on the show.
“I’ve known Tyler for years, we’re great friends," Vince told The Sun. “He was like, ‘Amy was a fan of you anyway and if anyone could do it you could’. ”
