St John’s Shaughnessy will be celebrating the 50th anniversary of dedication of their mighty Hallman pipe organ with a choral evensong (Ann Chen, Choirmaster), including works by Healey Willan (1880 – 1968), and festive organ voluntaries (Michael Dirk, organist). A revitalization campaign was launched last year which promises exciting renewal for one of Canada’s most significant instruments. The Royal Canadian College of Organists will offer historical displays and organ loft tours with pipe demonstrations during the light refreshments provided following the service.
