Mike Marshall's choro book has "Apanhei-te Cavaquinho" in it, and is a must-buy for North American mandolinists making their way down the choro path.
The choro jam that I recently started attending plays "Apanhei-te Cavaquinho" a lot, and it's finally starting to fall under my fingers (after a LOT of work). It's a blast once that starts happening. The B section, in particular, is really hard. The C section, on the other hand, looks like a total bear but it falls in really quickly and rolls off the fingerboard like a freight train.
