The restoration of a 150-year-old organ housed at the Maria Regina parish church in Marsa – which took three years to complete – is to be inaugurated tomorrow at 6 p.m. The organ was restored by Brian Bugeja. The ceremony will include a concelebrated Mass led by Mgr Charles Cordina. The pipe organ will be played by Dion Buhagiar and by Mr Bugeja himself. Also taking part will be the resident choir of St John’s Co-Cathedral in Valletta, the Collegium Musicum.
