You're going to LOVE the video below of the Makarines performing sevillanas live. The third copla they sing is an excerpt from this sevillanas and it has to do with the Rocío pilgrimage. Here it is:
Sevillanas (De: Porque El Relente Le Daba)
José Miguel Évora/Isidro Muñoz*
Porque el relente le daba
Le puse mi chaquetilla
Le puse mi chaquetilla
Porque tiritaba y yo la veía,
Ay!
