I've so far met, and didn't recognise the following people: -
Adele
Bowling for Soup
Tom Morello
John Fogerty
Dion Dublin
Jarvis Cocker

I can also confirm that the majority of WWF wrestlers are announced as being at least three to four inches taller than they actually are, Chris Jericho, as a prime example is closer to 5'10" by my estimate, rather than the declared 6'2".

Hulk Hogan has saggy nipples.

Apologies for beating around the bush with this bit, but I don't want my employer finding it: -
At a certain concert that was held at a Royal Park this year, I was dealing with the headline artists family and guests viewing area, this being the night when he had the plug pulled a little earlier than he would have hoped during a sing-song with a famous bass playing scouser. They were all lovely.

There's a hairdresser in Birstall called Adele's Barbers.
Tagline: "never mind, I'll shave someone like you".

They don't really have a tagline, I made it up for the purpose of a cheap joke.

Also, Dion Dublin invented the best of all things.
A revolutionary new musical instrument called THE DUBE.

How can you not recognise
Bowling for Soup? Their singer looks like Adrian Edmondson and they've got the fattest guitarist in rock (even fatter than me).

It gets worse.
They were carrying a large inflatable unicorn at the time.
