What happened to fiddlers of Scotland? Ended up in nova Scotia and I have heard that they had to reteach Scots fiddling from nova Scotia.

Bollocks.

What actually happened in Scotland is that we rounded up all the most credulous morons we could find and shipped them off to Canada (much like what happened to the telephone sanitizers in "The Hitchhiker's Guide to the Galaxy"). That's why Canadians, to this day, will believe anything.
