Talk:Duet concertina

The entries re duet concertina/Maccann duet are conflicting. The quote from Hayden gives the spelling "Maccann" as does the Concertina.com site which is linked to under the heading of "MacCann duet". The linked article re Maccann makes it quite clear that that was the way that he spelled his name, and uses that spelling throughout. Without going back over all the stuff which I have read in the last few months on the subject it was my understanding that somewhere along the line a capital C crept in, and was adopted to a large degree, but that it is now recognised that the non-cap C spelling is wrong, as indeed is the other "McCann" spelling. Should some explanation of this be made, as we have two spellings of the same name on the same page, and a link to a very comprehensive website which also uses the non cap C version of the name ... ???
