Because I do not speak Portuguese, I am unable to provide any more data than the following. I only recently heard this song on a MYOL-type station, and they said it was some type of samba by Sergio Mendes and Brasil 66.
At any rate, the chorus has the hook: "BAH, BAH, BAH, BAH".
Thanks a million to one and all.
