the War of Spanish Succession. Similarly 7 November is also remembered in Northern Catalonia after the Treaty of the Pyrenees. Dance and music Among the musical traditions, there is the very special music of the cobles, the wind bands that play sardanes. The sardana is a circular, open dance, that originated in the Empordà region (north of the country by the Mediterranean sea) and the Pyrenees (Catalan Pirineus), and is now danced in many squares and streets all over Catalonia. Popular folk songs include "El Rossinyol", "La Balanguera", "La Santa Espina", "Virolai" and "El Cant dels Ocells". Some of them became something like unofficial national anthems under the years of General Franco's dictatorship. Some of those songs became popular all over the world with the success of the Orfeó Català choir around the beginning of the 20th century. Another song, created by the present singer Lluís Llach, L'Estaca, also gained sudden recognition as expressing the national feeling of Catalans. Despite its relative recent introduction, singing l'Estaca became a kind of tradition. Another important Catalan musical tradition is the singing of Havaneres and burning rhum together at the Cremat which often happen simultaneously. Culinary traditions There are a number of Catalan culinary traditions, some of them coincide with a religious festival, like cooking a big Christmas Day meal on 25 December which includes escudella i carn d'olla. St. Stephen's Day on 26 December is a holiday in Catalonia. It is celebrated right after Christmas, with another big meal including canelons stuffed with the ground remaining meat of the previous day. These events are usually celebrated along with kin and close friends. Other religious event related foods include the Panellets sweets eaten on All Saints' Day and the Bunyols de Quaresma puffy little buns eaten to celebrate Lent. One of the most representative Catalan gastronomy-centered events is the Calçotada. This is a group event where a certain type of tender onions (calçots) are barbecued outdoors, among much feasting and merrymaking with family and friends. Similar occasions may be the Costellada and the Botifarrada, where mutton ribs or botifarra sausages are barbecued. Sometimes people also get together to roast pine kernels or chestnuts; the latter is known as "Castanyada", and it is a favoured event in the fall. The Vermut is a tradition, of having a light aperitif with olives and potato chips before the Sunday meal (formerly after going to church) together
