Above, a demonstration of the cha cha cha by members of the Associacion de Pachucos y Rumberas, in the Barrio del Peralvillo, within the Barrio de Tepito, within Colonia Morelos, within Centro -- more or less -- in Mexico City, on 20 March 2010.
The cultural center where the event took place functions as a gallery featuring local Tepito artists. Neighborhood folks came out to take a look. At one point, the pachucos -- in their Chicano-style drapes -- led willing observers in a short cha cha lesson. (My mom, Norma Alicia, got up and gave it a shot.)
