What's the ref's name? I love that he looks like he spent 30 years in prison for mauling someone to death, but has this super soft, gentle voice

I've had a pet project for a couple of years. Back in 2019 a Friend of mine gifted me an original copy of "Joe Davis: How I Play snooker" and over the last number of years I have ammased a number of autographs from the pros including Ronnie O'Sullivan, John Higgins, Judd Trump, John Virgo etc..

Tonight I added Mark Williams to that list. He signed for me at the NI Open in Belfast. Really nice guy to talk to.

I just need Hendry, Dennis Taylor and Steve Davis to complete it.
