What dance festival is celebrated in Obando Bulacan and can be attended by a couple who wants to have child?

The rites are observed in a triduum: 17 May for St. Paschal Baylon, 18 May for St. Clare of Assisi, and 19 May for Our Lady of Salambáo. Each of the three days usually begins with a morning Mass said by the parish priest. A procession, held immediately thereafter, consists of the three saints' images followed by bands playing instruments made of bamboo or brass, and devotees who dance the fandango while singing the hymn, Santa Clara Pinung-Pino (Saint Clare, Most Refined). The image of each saint leads the procession on his or her designated feast day.

The rites, especially the fertility dance, are popular with pilgrims from all over the Philippines, most of whom supplicate the triad of saints for a child, a spouse, or general good fortune. Throughout the three days, devotees joyously dance in the streets as a form of prayer, asking for the spirit of life to enter into the wombs of women.
