Stephen,
Unfortunately religious fanaticism exists in Scotland to this day. I never really read much about Calvin, as we had our own version of his doctrines, which I decided weren't for me. The history of Scotland is complex, and my own family tradition meant that we had nothing in common with Catholic kilted Highlanders, who were used in an attempt to eradicate Presbyterianism from the lowland areas in the 17th century. To this day I'll never wear anything that is tartan, as although I don't have any religious preferences, some of my civilian Scottish ancestors were beheaded by Highland Scottish soldiers on account of their religious beliefs. Certain Scottish Presbyterian families, as well as some Calvinists who had sought refuge in Scotland from Mecklenburg in Germany, fled to Ireland to avoid the risk of execution. It's a very long story.
Harmonica was very popular in the 50s in Scotland, but very few kids bother to learn it these days. The price of a decent harmonica came as a surprise to me, as a brand new double sided C/G Hohner Echo could be had for the equivalent of about 10 Euros in the 50s in the UK. People used to buy them as cheap Xmas presents, but they aren't cheap any more.
Dancing is pretty cheap, although I have noticed in recent times that it is not obligatory for a man to dance with a woman. Wonder what Calvin would have made of that?
Thanks for the link to Joel Andersson's website. Wonder how much a Guinness would cost in Sweden?
