In this period of time, the club became popular for its theatrical activities, held at the club's premises itself. The club even had its own theatrical company. The dedication for theater work was so passionate that at a stage in the late 1930s, the club considered investing in a new theater inside the club. Yet, this idea was put off as a war was nearby. In fact, when the Second World War took place, all activities in the club froze. The club's premises was converted to a center for the A.R.P. and it greeted British regiments. The members of the club still met at the house 85 in Sanctuary Street. After World War II, the pharmacist Sir Arturo Felice was elected as the club's president, whilst the committee was planning on how to regain the life the club once had before war. The first project it came upon was the building of an outdoor theater in the club's garden. It was a pretty ambitious project by the club's members, yet they rolled up their sleeves with the greatest of enthusiasm. The project lasted three years and was given the name of "Blue Arena". The theater's capacity was of 650 seated spectators, and its name became pretty known around the islands for its number of theatrical works done. In March 1943, Priest Guzepp Zarb was given the role of Parish Priest, and immediately, he rolled up his sleeves and worked hard to crown the blessed painting of Our Lady of Graces, a true work of art by Alessio Erardi, finished in 1715. The dream of every single person from Zabbar became reality when, Archbishop Gonzi crowned and blessed the painting on the church's parvis, in front of an extremely large crowd. In this year, big feasts were celebrated, where both band clubs took part of. The club also released a hymn for the occasion. Maestro Joseph Abela Scolaro was in charge of the music, whilst the monk Mattew Sultana, wrote the lyrics. Monk Mattew Sultana was also the spiritual director of the club. The hymn was first played publicly on 26 August 1951, in Sanctuary Street's square. In 1983 the club celebrated its 100th year. A program of activities was planned. It was in this period of time, where youth participation increased. The youth inclusion resulted in a boost in decorations for the feast, and other occasions, like Christmas. In fact, for three consecutive years, the club won the national competition for the best decorated street for Christmas, and also the national competition for best decorated facade for Christmas.
