The judges also praised singer Isaac Waddington, with Cowell saying: "Isaac, that was fantastic. Fantastic. No gimmicks, no tricks, but what I loved about it was you were in complete control of the song.
"You have improved so much from when we first met you. I thought I knew who was going to win and I may have changed my mind now."
Old Men Grooving's wedding-themed performance was a hit, with Dixon telling them: "That was great fun. You guys are fabulous."
Lowlights included Calum Scott forgetting his words during his rendition of Rihanna's hit, Diamonds.
Cowell said: "It fell apart the first part of the song. Luckily on the second half of the song you picked it up. So, all I can say is I hope that people judge you on the second half."
