The 32-year-old star released the double A-side `Anything Is Possible` and `Evergreen` when he won TV talent show `Pop Idol` in 2002 but hasn`t ever performed the first track lives because he dislikes it so much.
He said: "I`ve never done `Anything is Possible` live. I hate it. I absolutely hate it."
The `Come On` singer is known for his quirky music videos but admits he "can`t bear" to watch back his first ones because they were so "shocking", despite having huge amounts of money spent on them.
He said: "I can`t bear `Evergreen` or `Anything is Possible`, they`re absolutely shocking. And you wouldn`t believe the amount of money that was spent on those videos. F**king hell! Dreadful videos. At one moment it looks like I`m in love with a tree! Dreadful. Really odd. Dreadful. No, no, no. No. But since then the track record has been pretty good actually - apart from one - but the first one was really awful."
While he never performs `Anything is Possible`, Will still plays `Evergreen` live but enjoys experimenting with different arrangements of the track as he thinks it is "important" to continue to sing the song.
He exclusively told BANG Showbiz: "I just thought, let`s do something a bit more interesting. Originally I wanted to do a really dancey `Evergreen`, which still could work one day. But Dave my MD [Musical Director] came with these chords, and it`s nice to... it`s a song that`s so different to what I`m doing now but it`s important and it`s a moment and it`s good to do, so we change it up and it works."
