I, too, have heard James Galway play dance tunes, on flute, and I think that he played them well, if, perhaps, self conciously. As a classically trained artist, he can, only, play the trad style from imitation and impression. He plays, if you will, with a bit of an accent. In a previous posting, I mentioned Itzhak Perlman's foray into the world of Klezmar. He was terrific but stylistically flawed. He couldn't help himself. He has a low shmaltz tolerance and klezmerim have to shmear it on with a spatula.
But, full credit to him. He loves the music and the tradional rituals. So does James Galway. Let's cut these guys some slack. They honor their roots and they honor the music we love.
