We could never reasonably house a piano in our wee flat. The old harmoniums you can buy for almost nothing on eBay look churchy to the point of spooky-gothic. Those Indian portable ones sound a bit crap. Why not a piano accordion? I love the sound they make. Years ago, I used to hang out with a group of blokes who played Irish music in pubs. We had some great times. Of course, being a non-musician I was always on the fringe. They were always encouraging me to learn to the tin-whistle, but back then I was more interested in drink and skirt, and didn't have the patience to practice. The piano accordion was the heart of the group. It seemed very intimidating then, but now it looks playable. Voila.
