Over the years, Haydn has arranged or adapted a number of choral items which have been performed by individual and massed choirs at concert venues, as well as being used to lead the singing at sporting events. The majority are for male chorus (TTBB), but Haydn has also scored certain items for mixed voice choirs (SATB).
Haydn has also adapted the National Anthems of many countries, also for use at sporting events – these have included Argentina, Australia, Canada, England, Fiji, France, Georgia, Ireland, Italy, Japan, New Zealand, Romania, Samoa, Scotland, South Africa, Tonga, USA and Wales.
The ‘Anthem’ from the musical Chess’ and ‘Working Man’ have been published by Banks Music, as well as a co-arrangement of ‘Let it be me’ with David Last.
