In 1982, as a student, I was travelling from Venice to Athens on a train through Yugoslavia. The journey took 40 hours so all the young people shared their food and got to know each other. One Venezuelan guy was very popular because he had a guitar. I told him I was from Leeds, not expecting him to have heard of it, but he shot back, "Do you know Gabby Jones? She's my aunt." Out of three-quarters of a million people, I did! Not only that, I had to remind him what his uncle was called.
The funny thing about the coincidence was how it struck the two of us so differently.
