I like that pun, 'spaw. As in "If it ain't baroque don't fix it."

This isn't what you're looking for, khandu, since there aren't any guitars in it, but there's an Irish group called Dord n that I'd recommend to anyone who agrees that Mozart and Haydn and Bach belong with Carolan and good session music.

But maybe if you had some idea of what the pieces were or who might have written them that might help people point you in the right direction, if they haven't alrady done so. (Though I always find if I look for one thing, I find something else, so maybe it's best to start looking for something that isn't quite what you're after anyway.)
