I agree that Gaelic is a pretty good language for singing. That I don't understand any of it isn't a problem for me.
Here in Holland there are about nihil folks that can speak Gaelic, I think. Folks in province Friesland (1 of 12 Dutch provinces) speak Frisian though. It's a separate language from 'normal' Dutch and most folks outside that province cannot comprehend it mostly.
And qua TV, which I absolutely love, we have numerous foreign channels. Several US ones, 3 or 4 UK ones, 2 Belgium ones, 6 German ones, 3 French (1 is Arte but it's been dubbed in German), a Spanish, Italian and even a Turkish one. I have a thing with languages, I believe.
