Well, as an Englishman, I'm ashamed to plead guilty of the charge of abusing a concertina, by making it play Swedish, Norwegian, French, Belgium (Yes! Belgium!!) tunes, as well as English. (and a bit of Jazz too!)
I hope the court will look kindly on me, and I accept any sentence that it sees fit..(And may the Lord have mercy on my soul)
