Theres a short biog of Bandmaster Green in the Hampshire Advertiser of 1 Sep 1900:
[summary] b. 1853 at Cork (perhaps not true, see first topic post), son of of Sgt-Mjr in the 8th [sic, edit: 5th] Dragoon Guards who fought at Crimea and was awarded medal for conspicuous bravery in the charge of the heavy brigade; joined band of the 8th Hussars when 12; learnt clarinet at Kneller Hall; returned to rgt. and became band-sergeant; qualified as bandmaster at Kneller Hall; 1879 appointed bandmaster to 10th Hussars in India, until 1887; chosen as bandmaster of the Duke of York's School; Feb 1897 selected as bandmaster for Royal Marine Artillery; daughter, Bella, an accomplished pianist; Green was also a composer ('Eileen', 'Memories of the Past', 'Sunny Southsea', 'Benin', 'HMS Powerful').
In 1906 he was awarded the Royal Military Order Notre Dame de la Conception de Villa Vicosa (3rd Class) by the King of Portugal.
He became musical director for the Royal Marine Artillery in June 1914, with the honorary rank of Lieutenant.
It also seems his band was a favourite of Queen Victoria when at Osborne, King Edward when on his yacht Victoria & Albert (he gifted to Green a diamond pin), and when the King and Queen went to Delhi they took his band aboard the Medina.
Anyway ... I got sidetracked ... I was trying to find out if he was in Afghanistan!
