If you can find a decent SMF of the tune, you can always cut out the Intro and splice it into your favorite style for the song... if you want to go with the slowed down Samba, for instance. Or even grab Ian's Intro from the Bossa version.

Mind you, the sax solo in the middle is a bear to get the scoops right while still playing the chords with your LH. In this particular song's case, if you are shooting for authenticity, an SMF might do the trick better than a style.

You can still drop in some Markers so that you can extend or shorten it on the fly, should you feel that necessary.
