Does anyone know how I can meet John Barrowman? He is great but I can't find how to meet him :(?

I live by Liverpool and John is never anywhere near me because he is always in America or Cardiff, does anyone know any events near me or any way I can meet or email him or something? I have his autograph but i have never met him, although I went to see him in Aladin (which was fab) and Ihave looked all over the web and can't find a way to meet him. Can anyone help?
