So here are some from me. Which one of these is the truth...?

One statement is true and the other two are lies

(PS I have done one of these before so I won't do the Monk one again)

Statement 1...
Ex Doctor Who Sylvester McCoy once thought I was a woman

Statment 2...
I have appeared as an extra in a Spandau Ballet Video

Statement 3...
I once applied to go on Countdown but diodn't make it because in the audition I failed the Number round!

So which one is true?
