Joaquina Carreras sings folk song “Triste está mi rancho”, then Giménez and Suárez (“genuine northern dancers”) dive into an enthusiastic folk tap dance. After them, Julio Perceval (“delight of Buenos Aires citizens’ ears”) executes a piano solo, and “graceful interpreter” Anita Palmero sings the tango “Botarate”, by Acuña and De Cicco.
