Daniel Johnson was on the 2012 series of The X Factor UK, mentored by Nicole Scherzinger. He made it to the Judges' Houses stage, but was unfortunately eliminated before the live shows.
While he didn't win or make it to the finals, it's hard to say how "well" he did in the broader sense. It all depends on your perspective:
* From a competition standpoint: He didn't progress very far, but that's not uncommon for a talent show. Many talented contestants get eliminated early.
* From an impact standpoint: He definitely gained exposure and a following, and might have had the opportunity to pursue music further after the show.
Unfortunately, finding detailed information on Daniel Johnson's post-X Factor career is limited. There aren't many recent news articles or social media presence for him.
I hope this information is helpful!
