Query: Best Jobim vocals, ever!

Yes, the musicianship is great. Both versions of "Brasil" are legendary, and the instrumentals blow you away everytime. But what about the most stunning piece of music in the album, the delicate yet powerful "Sabiá"? Jobim and Chico Buarque wrote that song in collaboration, that should be enough for you. But the delicate instrumentation combined with Jobim's trademark raspy voice turn the whole song into something very hard to forget.
