So I got this Whistle Tutor Book maybe back in the mid 90’s. It had alot of really great Tunes, some wellknown and some not. I loaned the Book out to someone at a session and never got it back. I’d like to get a another Copy. I don’t know the name of the Book. but it had a somewhat stocky Gentleman on the Cover playing maybe a Generation whistle presumable at a session. He had long dark Hair and a Tweed type driving Hat The Cover was glossy White.. Anyone have any idea of the Book in question? A quick google search did not pull it up 
Well digging a little deeper on Google I found and ordered an old copy of the Book. Its Geraldine Cotter’s Tradition Irish Tin Whistle Tutor . I believe its still in print and readily available Even if you play the Whistle i would recommend this Book as its got alot of great Tunes, some well know and others less so This was actually the very first Tunebook I came across, well before I played any Sessions. I think it may have first been published in 1989. I thnk I also got Oneils around then, but did not use it as much as Cotters Book.
