Dear John,
Indeed, these pieces are very rare. In fact, I wouldn't know about them if I weren't researching Nazareth's works and discography for the past 8 years. Everybody knows Odeon, Apanhei-te Cavaquinho, Brejeiro and Escorregando, which are his top most recorded pieces (along with Dengozo). Some people know Batuque, Ameno Resedá, Bambino, and Matuto. But basically no one knows A Fonte do Lambary, O Nome Dela, Pirilampo, and Furinga. This is because the latter group has never been recorded commercially. As a matter of fact, from the 211 existing Nazareth compositions, 61 have never been recorded on disc.
You can find a list of his complete works here:

You may feel free to ask me for his scores. I can scan them and send to you. Just take a look on the list and mark the ones you'd like to know.
All Nazareth pieces but 37 have been published on printed scores in some point in history. But just a few of them remain in the catalog of some publishers today. To get all of them you must resort to collectors or Brazil's National Library (
www.bn.br), which has almost all his scores + rare manuscripts.
As you'll see, Nazareth has still some hidden masterpieces waiting to be discovered.
Cheers,
Alexandre
