What was your best subject? Architectural drawing and woodwork.

What was your worst subject? History and geography - I'm fascinated by those subjects now.

If you were choosing subjects for Leaving Cert today, what would you choose? I would not change my subjects but I would pay more attention in geography. When I was travelling the world with Boyzone I didn't know where I was half the time and I'm disgusted with myself now. I'm always looking at atlases and trying to retrace my steps.

Would you send your own children to the same school that you went to? Absolutely.

What was the best thing about your education? I never needed any of it!
