What's the name of the French harp book, and who is it by?

Also, remember that a number of tunes have been credited to Carolan over the years which are not actually composed by him. The O'Neill collection from the early 20th century is one such source of confusion (music's still good, though).

Are you sure that the air in Paret (which is not a historical source) referred to in the first post is the same as the one in the French book? "Carolan's Air" is only a generic title, and he wrote a lot of airs! If you have a way of giving us the melody - either to read or hear - it would enable us to be of more help.
