Now that I think about it, my brother Tito has a page about Costa Azul and the Festival Rumbon de barrio. He has a photo of Aaron posted on his site. There are also a lot of interesting photos of the Rumbon de Barrio you might like.
At the bottom of the 1st page he has a link to his forum, you could ask him personally, although I told him, he may forget, in that way you can remind him. Click below to go to the site.

Either way, when me or my brother see him we will tell Aaron you all said "Hi".
Sincerely,
Eddie
