Madness performed some of their hits during the X Factor final.
The band treated the audience to their new single, Mr Apples, from their latest album Can't Touch Us Now, before launching into their hits Our House and It Must Be Love.
Lead singer Graham McPherson, also known as Suggs, plugged their new album before departing his advice for the finalists.
He said: "I always say the same thing and it's basically just keep going.
"You see so many young bands split up at the first hurdle. If you don't keep going you'll never know if you would have made it."
