CROWDS for the 14th annual Organs of the Ballarat Goldfields are continuing to grow.Several performances held at the weekend were packed with organ enthusiasts keen to hear, and see the skills of world renowned players like Thomas Heywood, Shu-Cheen Yu and Anthony Halliday.For the first time in its 72-year history the Compton Opus 379 theatre organ at Her Majesty's Theatre was played as a classical instrument on Saturday.The organ first appeared in the festival several years ago, but was dumped because its sound was not to the liking of organisers.Ballarat Theatre Organ Society president Paul Forte said it took several hours to tweak the organ so it could be played as part of the festival."The festival is generally strict classical music," he said."This being a theatre organ was mainly played during silent films so it's being used for a very different purpose to what the audience would normally hear."We found Thomas (Heywood) and asked him, being a strict classical organist, and he has completely changed all the registrations on the organ, resetting the sounds to play just classical."On Saturday the performance of Mr Heywood was mostly full as listeners crammed Her Majesty's Theatre.The festival runs until January 18.
