Hi Dec,
I think that's the very LP I mentioned. If it has a souped up version of "Pigalle" on it then it's the same one.
I actually bought the LP from Jimmy Clinkscale, but it disappeared along with my first wife, along with several other of my possessions.
I've seen Fintan on You Tube with another CBA player using a French box at what looked like a wedding venue, either in Ireland or in the US, and he plays a selection of decidedly non-Irish material in the clip. I remember thinking "How did he get away with that with an Irish audience?" In hindsight I think it might have been in the US, as I seem to remember another clip of him with the Tommy Mulvihill band, who I believe is a US born musician of Irish descent.
The only pro Scottish player I know of who openly turned his back on Scottish music for swing/jazz/musette is/was Tommy Kettles, who played a big Cavagnolo Vedette 10 CBA, which I think was LMMH. I heard him playing in a French restaurant in Edinburgh, and he was superb. However he only got a handful of tunes over before the crowd demanded that he play a few Scottish tunes, which he did very much tongue in cheek. A guy at the next table commented that he should ditch the Cavagnolo and get a real accordion that could play Scottish music. I reminded him that he was actually in a French restaurant, and he reminded me that he was 6'4" and 10 years younger than me. His friends were looking for trouble so I never said another word all night.
At that point I decided that I'd better confine myself to playing my "Continental" music at home, as I knew it wouldn't go down as well as the drink at any of the local venues.
I haven't heard much of Fintan recently, but he could certainly handle a CBA, whether he was appreciated by the home crowd or not.
