> It would marry well with traditional Irish music and culture.
A musical culture that would not exist as it is today without Travellers, who have not only produced some of the most well-known and influential traditional musicians (John Doherty, Pecker Dunne, Paddy Keenan, the Fureys, John Reilly to name a few), they became both keepers of the flame and a source for revivalists when traditional music and singing waned in popularity among the settled community. Uilleann piping owes a lot, possibly its very existence today, to Travellers, and a lot of songs that bands like Planxty and the Dubliners played were sourced from Travellers. One of the reasons they're so wary of bringing outsiders in is that plenty of outsiders have come in before, made their recordings/interviews, then fucked off never to be seen again, making money from the cultural capital collected from Travellers.
I'm not trying to jump down your throat when I say this, but honestly, take a second and learn a bit. It's well-documented. If people (not necessarily you, but in general) actually knew about some of the history behind this shit, we wouldn't get the same exact ignorant/uninformed comments every time Travellers are mentioned.
A book called <em>Free Spirits: Irish Travellers and Irish Traditional Music</em> is a good intro to the many Traveller musicians who have made an impact in trad over the years. An American anthropologist couple, the Gmelches, have spent a considerable amount of time with Travellers, and their book <em>Irish Travellers: An Unsettled Life</em> is fairly well-done, giving a good background on Traveller history and contemporary issues. And if I may do a bit of shameless self-promotion, I made an audio documentary a few years ago focusing on Traveller singing and music.
