I am glad to hear it is happening in some other places. I know that it is alive among some of the ethnic minorities in Germany. If there is a wedding, say Greek, Turkish or Polish, they are likely to have music and dancing from their culture. German folk music is the last thing you would expect to hear at a German wedding - and sadly, the idea of hearing English folk music at an English wedding would raise only a snigger of ridicule.
I have made it clear enough elsewhere that I have no nostalgia for the Irish Pub scene. One thing did impress me though. If you get a group of Irish guys sitting around after hours, they are quite likely to start singing some of their songs. Some will be old and some will be new. The tradition is alive and well there because it is something which has remained unbroken in their culture. Get a group of English people sitting around, and most would be embarrassed to admit that they knew even one folk song. They usually regard it as quaint and silly.
The practice of coming together and making music - learning old songs and tunes, changing them and adding new ones is practised by only a tiny minority. It is encouraging to hear that it is flourishing in other parts of the world, but I don't see much evidence that it is surviving in Germany or England, the two countries which I know best. I do not really want to get all my music from machines - but it puts me in a very small minority!
