Note:  Corrales Viejos is a neighborhood in Buenos Aires next to Parque Patricios, where there used to be corrals - hence the name. It's an area considered to be the crib of Argentine tango and where many dancing happened in 1800s. Speficic name of places where tango was danced are mentioned in the lyrics such as Humberto Primo, La Cancha De La Tapada (cancha means pitch or field, tapado/a means covered so maybe it was outdoor space with a tent).
