If you look at the results of the Hankiralli (snow rally) in Finland for 1976 you will see that several awards were won by David Hardcastle (UK) and Seppo Harjanen (Finland) in a Ford Capri 3 litre. Seppo had a daughter and a son, who was then aged about 5.
Despite the successful event, the 2 were never in touch again. David retired from the sport 2 years later and Seppo went on to be a professional co-driver at world championship level.
In 1994 David emigrated to Thailand and still lives in the northern city of Chiang Mai. There, in a bar very near his home in 2005, the Scots bar owner John Whiting (a witness to this concidence) asked for help in understanding a drinks order from a man with heavily accented English. David realised the man was Finnish and greeted him in his own language.
Amazed, the man asked how he knew some Finnish, and David briefly told the rally story. At the name of the co-driver, the man's jaw visibly sagged.
"This Seppo, he was single, yes?" demanded the man.
"No" replied David, "he was happily married with a son and a daughter."
"Yes!" exclaimed the man, "and I am the son!
