Once saw Paul Daniels stuck in a traffic jam on the A1 (as I filtered past) he looked really old.
Many years ago saw Alexi Sale riding a bicycle through central London and the same night was in an elevator with Kenny Dalgliesh (he was wearing a kilt).
When I was a kid I used to walk past Kenny Burns' house on my way to school.
Some of my friends knocked on his door and asked for his autograph. He told them to **** off
