Loads of instrumental tunes with Canadian placenames in their titles. Look at Paul Cranford's Lighthouse Music site for the Cape Breton ones (though it can sometimes be hard to work out whether the tune was originally meant to relate to a place in Canada or to the place in Scotland it was named after).

I tried looking for the Mouth of the Tobique on Google Earth (it's the name of a syncopated reel often used for contra dancing). It's a boring river junction surrounded by swamp which seems to be known only to sport fishermen. So how on earth did it get a tune named after it?
