A story once told to me by the late Tony Capstick.
Tony many years ago met the singer Noel Murphy and they agreed that if Tony was ever down in London he should contact Noel and they would have a pint or two.
Some time after, Tony was working for a few days in London, but he had lost the number and decided to look him up in the phone directory and sure enough there was a Noel Murphy listed.
Noel    "Hello"
Tony   "Hi Noel, its Tony Capstick. How are you"?
Noel    "Tony, well I'm fine. How's yourself"?
Tony    "I'm in London and I thought you might fancy a pint tonight".
It was arranged the two would meet at 7pm in Noel's local pub.
At 7pm Tony is stood at the bar in an empty pub, when a bloke he had never seen before walked in and made his way over to him, and asked if he was Tony Capstick, Tony a little confused said yes.
Noel    "Nice to meet you. Noel Murphy".
Tony    "Likewise, but there's some mistake, I thought you were Noel Murphy the folk singer".
Noel    "No I'm Noel Murphy the plasterer, but we're here now so we may as well have a pint".
After a few pints Tony asked him, why he had arranged to meet somebody he didn't know, and Noel said "I said to me wife he seems a nice enough bloke, so I thought why not".
They kept in touch and remained friends for many years

Tony told me this story in hotel room at about 3am in the morning after we had seen off a bottle of scotch, I think I get right.
