I probably wouldn't recognise them if I did.
To me, celebrities are just people I don't know.

You must recognise some.
Sean Connery? Alex Salmond? Billy Connolly? Jackie Stewart? Lulu?

I don't remember ever seeing any of them in the street,
so empirically, no.
I don't think I'd even recognise Simon Munnery, and I've spoken to him.
