4 September 2004.
Episode 2 of series 5.
Steve Brookstein
I'm assuming their first live performance (other than the broadcast XFactor) was the XFactor tour, as they're album didn't come out until November 2009
On the first day of auditions because he was first in line.
There was no xfactor 2001 because it started in 2004!!!
He is very popular. He came in first every week on Xfactor.
Matt Cardle
The first time was when they performed torn on the Xfactor, Judges house.

The Xfactor final is the weekend of 12th December
What Makes You Beautiful but their first song to sing was Torn in The XFactor 2010.
