Some of the points I was trying to recreate are: the eights notes on the ride or the Hi-Hat, the Hi Hat openings with the foot or the sticks, the phrasing over the bar lines, and the interaction with the soloist (in this case, Rosa Passos and Paquito D'Rivera). Paulo plays the HH on the down beat and then the up beat without notice, which really spices up the groove. To play along with Paquito or Rosa is such a pleasure because they are playing deeply within the groove but free with the melody at the same time .
About the song itself, "o pato" means "the duck" in Portuguese. That is a light and funny subject so, I don't see any reason to be serious playing this! You have to have fun:-)
