The Voice: Sam Buttery and Sophie Griffin are first contestants to leave Sam Buttery and Sophie Griffin were the first unlucky acts to be voted off The Voice last night following Saturday's live show. Buttery's star coach Sir Tom Jones chose to lose the 20 year old Londoner from his team even though his performance of Erasure's A Little Respect was praised by all four coaches. Viewers" votes put him and folk duo Matt & Sueleen in the bottom two following their live debuts on BBC One. "I've just learnt so much from him [Jones], he's been around in the music industry twice my lifetime," said Buttery after his fate was revealed. The knowledge you get from that is just invaluable, and I'm really grateful for that. I'm just sad to be leaving really. Meanwhile, rival coach will.i.am reluctantly decided to lose 17 year old Griffin, whose rendition of David Guetta's recent hit Titanium evidently failed to impress the voting public - she found herself in the bottom two with soul singer Joelle Moses. "This has been the best experience of my whole entire life," said Griffin. I've learnt so much, and I've worked with some of the best people in the whole entire world. Both coaches now have four acts left in their teams; Matt & Sueleen, Adam Isaac, Leanne Mitchell and Ruth Brown remain in Team Tom, while Joelle Moses, Frances Wood, Jaz Ellington and Tyler James are in Team Will. Next Saturday, Jessie J and Danny O'Donoghue will see their teams perform live for public votes for the first time.
