I do have to admit that I've been to Paris a number of times and somehow there seems to be a lack of traditional accordion music heard there. Unfortunately you hear poorly played accordion music by people essentially begging for money. My fantasy would be to pick a small square there, perhaps in the Latin Quarter, nestled between a few small restaurants and just play a few tunes because this would add to the ambiance and make my trip complete. However the experience would be sufficient without the need to earn any money.
I've also suspected that some (not all, but many) of the busking accordion players I've seen in Europe are essentially deluxe panhandlers, who only know a few simple tunes--one is always "Never on a Sunday" for some reason--and play them over and over and over.
But I once tipped one in Graz, Austria and after chatting with him for a bit, he let me "take over" for a few tunes. So I did briefly get to busk and hopefully add to the ambience of a charming old European town. It was a trip highlight!
