Who is The Colonel?

Well I've been watching some Wimbledon over the past few days, and something has been intriguing me. When the camera shows shots of the crowd at centre court I keep seeing this gentleman who I have named the Colonel. He's pretty old, white hair, large yet well groomed moustache. Smartly dressed in a blazer and the clinching factor, he's always wearing a Stetson.

So my question to the 606 community, who is this man?

His name is David Spearing and it is his 34th year of being at the Championships. He lives in Abu Dhabi for the majority of the year before coming over to take up his position in the box. His job is to make sure everybody is in the right place and assists the players’ representatives.

thank you
