I'm in the UK and going forwards from late 60s/early 70s to date, I've met, grown up/worked/volunteered alongside a fair few 'recognised whoevers'.
I can't give names for various reasons but includes royals/ politicians as well as the lowly actors/singers/footballers etc. If I had a wish I'd love to meet and get to know Keanu, he really intrigues me. Seems such a lovely bloke. Too many carry the badge of 'Me myself I' where he's totally the opposite.
But, that aside, I've met some lovely recognisable names who I've really admired, who've given their time to help in some way - without fanfare or wanting recognition for their input.
Many over yonder might not know of my choice - Patrick Moore, the astronomer.
He's a once met, never forgotten type - lovely, blustery, totally nutty as a fruitcake and terribly eccentric who inspired many to take an interest in astronomy. Not being unkind, but his attire always reminded me of something Barry Humphries character, Sir Leslie Colin Patterson, might wear
On April Fools Day 1976 he did....
The Great Gravity Hoax of 1976!
A longer, in depth video of him if anyone wanted to watch:
