In keeping with the El Goyo birthday celebration, here is a nice (if a bit hard to see) clip of the CFN doing "Mama'buela," featuring Goyo on vocals. This is normally classified I believe as a "rumba de tiempo España," or a "rumba mimética," very old forms of rumba involving pantomimed dancing.
Even if you don't speak Spanish, It's pretty obvious what is going on here. The little boy doesn't want to go to school and Mama'buela is going to administer some old-fashioned persasuion techniques to change his mind. I know it's hard to make out the details in this, but the choreography of the dance is pretty clear. If anyone has a better copy, feel free to send it on.
In the meantime, if you want you can download this version.
