Moacir Santos wrote one hit from his Coisas album that was covered by everyone in the 1960s. The Afro-Brazilian jazz genius's "Nana" is but one instance of his splendid writing. Check out this early version here. Os Ipanemas, a samba-jazz group, also recorded a cover with lyrics in the beginning that's worth hearing. I also highly recommend Wilson Simonal's vocal version, from his bossa nova period. He's Afro-Brazilian and a great singer! And last but not least, Edison Machado recorded a decent version, too.
Here are other versions I like less, but still worth hearing
Mario Telles
Eurmir Deodato actually does a good cover.
