I think that many of the difficulties that the rest of you have pointed out in regard to Scotland in general and Gaelic Scotland in particular - such as the "Celtic Twilight" and "stage Irish/Highland/Scot" syndromes and the repression of vernacular languages and dialects.

In regard to perceptions of Irish music abroad, I've heard Irish traditional performers - including members of Altan if my memory is correct - tell stories of playing in America to people who had completely different expectations of what they should be listening to, people who asked for songs like "Irish Eyes are Smiling" There is a song - search the Mudcat archives for the full lyrics - by Robbie O'Connell called "You're not Irish" which tells the story:
When first I came to the USA with my guitar in hand
I was told that I could get a job singing songs from Ireland
So I headed up to Boston, I was sure to be alright>br> But the very first night I got on the stage,
I was in for a big surprise
they said;

Your're not Irish, you can't be Irish, you don't know Danny Boy
Or toora loora loora, or even Irish eyes
You've got the hell of a nerve to say you came from Ireland
So cut out all the nonsense and sing McNamara's Band.

Aodh (and of possible interest to others who speak or are learning Gaelic)- Brian and I tried to answer your questions if you want to refresh the "Chead Mhairt" thread. And please have a look at An Bhean Eudach / Thig am Bàta in case you can assist with that thread.
