Re: Most famous person you have met???
Alf Ramsey - twice. Once at Newcastle before FA Cup tie 1968/9 (with his family / friends, not overly impressed with my insisting that Neil Young should play for England). Second time at a petrol station in St Albans around 1981, when he looked at me as if I was a piece of crap when I asked him to sign my petrol receipt (he didn't).
Lou Reed - Brixton Academy early 1980's. I turned the corner and there he was in front of me - I stood there speechless and he looked at me like I was a piece of crap, etc...
Paul O'Grady gave me the eye on the concourse at Euston Station once - I was scared to smile...
Famous people are usually quite disappointing when you see /meet them face to face.
I knew Dave Threlfall quite well before he got into acting and became dead famous - Top lad, 100% great guy, probably still is... he's a blue after all!
