The Band of the Oxfordshire and Buckinghamshire Light Infantry
There is short description of the Band at http://www.rgjband.com/1stbandhistory.htm
“The 2nd Battalion was still in England when war broke out in 1914, and Bandmaster Neville – who had earlier received his Long Service and Good Conduct Medal – switched to the 3rd (Reserve) Battalion at the depot. By 1915 he was leading a Band of 25 men and ten boys on a recruiting march through Oxfordshire; later that year a photograph of the Band shows it to be 38-strong.
It proved impossible to maintain such high numbers in peacetime with the demobilization programme, and a further photograph taken in Germany in 1919, after Mr Neville had rejoined his Battalion, shows him accompanied by just fifteen musicians.”
