There has been a lot of publicity recently about the possible demise of morris dancing. Much of this has emphasised the "Englishness" of morris dancing. This is also mentioned in the fim "Morris; a life with bells on".
Being English may be a positive aspect in England, and possibly in the USA. But not always in Wales. I’ve been morris dancing in Wales for quite a few years and it is clear from comments that the perception of most spectators is that morris dancing is English.
