I'm living as a musician in Rennes, France, and I busk all the time. The plus in a non anglophone community (besides being able to mess up the lyrics and no one knowing) is that just the fact that one is singing Irish songs, American songs, or English songs is a draw. Grandfather's Clock, Dirty Old Town, Cecilia are all big money makers. Plus, if one makes an attempt to play French songs (I stick to Georges Brassens), the French are so honored and so amazed that an anglophone has gone to the trouble, that they're sure to contribute.
