Hey Ian Way early in my quest to learn the harp I picked up a book by John Gindick. I believe the title was "Rock n' Blues Harmonica", and in the back section there is a long list of classic rock tunes that contain harp along with the key and harp required. I don't have the book handy at the moment but if your still interested I can retrieve it out of the attic and get a list to you. Charlie G.
