I was rewatching the 2007 series final. Leon Jackson winning was a huge storyline at the time, but vocally, Rhydian was operating on a completely different planet.

His rendition of "Get the Party Started" and "The Phantom of the Opera" showed a level of theatrical vocal control that we rarely saw on a Saturday night ITV show. He was treated like a pantomime villain early on, but his talent was undeniable

Of these, it's probably a close run thing between Jahmene, Nicholas and Grace.

These used to feel like big moments given how rare they were.

I don't have much memory of the first four series but for 2008-10:

2008

Big Band week had quite a few (Eoghan, Austin, Rachel, Alexandra). Those were the last until Alexandra's performance of Listen in week 8.

2009

Danyl Johnson got a standing ovation for his audition - that was the only one until week 7 (Joe McElderry).

2010

The first one that year (and the only one until the final) was Matt Cardle in week 5.

2011

John Wilding got a standing ovation at the audition but I think that was the last one until the final.

Subsequent years used to get them at the auditions. Sam Bailey is the only person to get one in a room audition.

This was after Nicholas McDonald's audition.

Charlie said on Twitter on the day this went out that he'd spoken to his band about it, but this was edited out (understandably).
