Spanish to English Art/Literary History type of dance event

This is a literary text referring to a baile de candil put on by a small town for soldiers in the war to meet local girls. There are MANY types of "baile de candil", and this type does not involve any actual candles (many bailes de candil do) or other particular ceremonies, but is simply a dance (like a "social") organized by an Andalusian town in 1937 where soldiers go and local girls go accompanied by their mothers and other chaperones. I want the English to gget across the idea of this "event", it being organized as a way for young men and women to meet each other, but have no idea what to call it in English. Any ideas much appreciated!
