24-year-old Jay won over both Will and Sir Tom Jones with his performance of I Need A Dollar on Saturday night, and had to choose between the pair.
Will told him: "I think I pressed my buzzer within the first four seconds because I know what I'm looking for, and my ear was like 'That's it!'"
Speaking after the audition, Jay said: Choosing between [Will] and tom was difficult because Tom is old school, he knows his stuff, so it was hard
"The deciding factor was that will turned straight around"
He added: "When you get recognition like that so quick, it's amazing."
