Tony Capstick used to tell this story, I wish I could do it like him:-

I'm walking through Sheffield, and this bloke comes up, he sez - Hey! It's Tony Capstick!
And I said, that's right
And he said, you sing and play the guitar abit...tell jokes - make peole laugh....
I said, that's right
He sez, can you take some constructive criticism? Honest constructive criticism.....
I said, all right....
He said, You're crap mate!
